摘要： An Information Handling System (IHS) has persistent memory device(s) coupled to a processor. Each memory device includes a first firmware image, version identifying information associated with the first firmware image, and device type identifying information. A firmware interface suite coupled to the processor has a firmware interface that is executed by the processor. The processor responds to identifying a trigger condition for automatic intra-system firmware update of a persistent memory device. The processor accesses the version identifying information and the device type identifying information for a first memory device containing the first firmware image of the persistent memory device(s). The processor associates the device type identifying information with device type information for a second memory device. In response to the first firmware image being different from the second firmware image, the processor selectively replaces the first firmware image on the first memory device with the second firmware image.

摘要： A method, an information handling system (IHS), and a system for capturing video data and serial data during an IHS failure. The method includes detecting, via a controller, an occurrence of a system event log (SEL) incident in the IHS. In response to detecting the occurrence of the SEL incident in the IHS, a data recording window is retrieved from a volatile controller memory. The data recording window contains video data and serial data for a time period up to a time of detection of the SEL incident. The method further includes storing the data recording window including the video data and the serial data for the time period to a non-volatile controller memory.

摘要： A method includes identifying a first output terminal of a radio frequency front end (RFFE) switch including a single pole input terminal and a number (N) of output terminals, the first output terminal selectively connected to a single RF band path. Each of the N output terminals is a component of a respective one of N throws of the RFFE switch, with N being greater than one. The N output terminals include the first output terminal corresponding to a first throw of the N throws and at least one additional output terminal not connected to any radio frequency (RF) band path. The at least one additional output terminal includes a second output terminal corresponding to a second throw of the N throws. The method includes forming a parallel connection between the single pole input terminal and the single RF band path. The parallel connection provides at least two parallel branches for routing RF signals being transceived between the single pole input terminal and the single RF band path.

摘要： A foldable screen assembly includes a planar electronic display that has substantially parallel and opposed first and second surfaces. A planar lens assembly has a third surface that is positioned adjacent to the first surface. A first optically clear adhesive extends between the first surface of the electronic display and the third surface of the planar lens assembly. A first area of the first optically clear adhesive is selectively cured to have a first modulus and a second area of the first optically clear adhesive is selectively cured to have a second modulus. The selectively cured first and second areas allow the foldable screen assembly to bend.

摘要： Embodiments of the present disclosure relate to an enclosure for a disk array. The enclosure comprises a chassis for receiving the disk array. Each disk in the disk array is enclosed by a frame. The enclosure also comprises a heat sink including a plurality of metal bars arranged on a bottom face of the chassis. Each of the plurality of metal bars is adapted to contact a respective disk through a notch in the frame of the respective disk, to position the respective disk and to transfer heat generated by the respective disk to the chassis. In the embodiments of the present disclosure, the metal bars may be used not only for reliable positioning of the disks, but also for improving thermal dissipation performance.

摘要： Cooling system of modular data center (MDC) has air handling unit (AHU) that circulates cooling air through information technology (IT) module(s). Transducer(s) sense first air characteristic value of cooling air directed to IT module(s) of MDC, the value being selected one of: (i) temperature value; and (ii) humidity value. AHU controller determines whether first air characteristic value satisfies first air characteristic criterion of one of: (i) a temperature value equal to or greater than minimum temperature threshold; and (ii) a humidity value equal to or less than maximum humidity threshold. In response to determining that first air characteristic criterion is not satisfied, AHU controller triggers supplemental heater to warm cooling air before cooling air comes into contact with IT module(s) inside of MDC to at least one of: (i) provide cooling air above minimum operating temperature of components within IT module(s); and (ii) prevent condensation.

摘要： A controller of an information handling system (IHS) performs a method to detect tampering with functional components of IHS. Following a last authorized configuration change of locally-available information handling resources, a unique code is generated and stored with a time-stamped system log entry in a system memory. Prior to transit, a system management audit (SMA) log snapshot is generated and provided to an audit device for separately conveying to a recipient of the IHS. In response to powering up at least the controller of the IHS after transit, a current SMA log snapshot is obtained that includes a current SMA log entry and a current unique code. Access by an audit device is provided to the current SMA log snapshot to enable comparison to the SMA log snapshot created prior to transit for identifying whether there has been tampering with the IHS.

摘要： A method of assembling a direct-contact, liquid-cooled (DL) Rack Information Handling System (RIHS) includes inserting a leak containment barrier in a node enclosure provisioned with heat-generating functional components. The method also includes attaching a system of conduits supplying cooling liquid through the node enclosure and including a supply conduit extending from a node inlet coupling and a return conduit terminating in a node outlet coupling. A trough of the leak containment barrier underlays a portion of the system of conduits of an LC node and forms a drain path to a drain port of the node enclosure. The method further includes mounting the LC node insertably received in one node-receiving slot having a rear section configured for blind mating of the node inlet and outlet ports to a node-receiving liquid inlet port and a node-receiving liquid outlet port positioned to be inwardly facing to the couplings of the LC node.

摘要： An antenna subsystem of a communication device has an open cavity including an inner opening and lateral and outer sides that define a cavity. The cavity is sized less than required for cavity mode resonance at a millimeter-wave operating frequency. A millimeter-wave antenna element placed at the inner opening of the hollowed section cavity excites evanescent electromagnetic fields in the cavity. A slot antenna is formed in a metallic layer of the outer side of the cavity. A metallic sectioned proximity post has a first section positioned adjacent to and spaced apart from the millimeter-wave antenna element to couple to, and conduct, the evanescent electromagnetic field. The metallic proximity post has a second section positioned adjacent to and spaced apart from the slot antenna to couple at the millimeter-wave operating frequency, enabling re-radiation by the slot antenna.

摘要： An Information Handling System (IHS) and method provide for a thermal controller receiving from a temperature sensor a current operating temperature of the at least one functional device. The thermal controller determines a first rate of an air mover based at least in part on the current operating temperature sensed by the temperature sensor and the instantaneous component maximum temperature. The first rate prevents the at least one functional component from exceeding the instantaneous component maximum temperature. The thermal controller determines a second rate of the air mover based at least in part on lifetime average temperature and the long-term average temperature target that is selected for the reliability level. The thermal controller controls the air mover to operate at a higher one of the first and second rates.
