摘要:
A system of at least one wireless access device in a local area network (LAN) having a plurality of transceivers. Each transceiver has a directional antenna positioned in a substantially circular array to communicate signals with a plurality of stations in a corresponding sector. Each sector defines a portion of a coverage area surrounding the wireless access device. The wireless access device has a network interface to a data network, and an array controller to control communication of data between the stations and the transceivers, and between the transceivers and the network interface. The array controller is configured to modify channel assignments so as to minimize channel interference dynamically.

There are disclosed traffic generators, methods, and computer readable media to generate packets for testing a network under test. A first parameter memory bank may be active when a first bank select data has a first value and inactive when the first bank select data has a second value. A second parameter memory bank may be inactive when the first bank select data has the first value and active when the first bank select data has the second value. One or more engines may generate packets based on parameters stored in the active one of the first and second parameter memory banks. A processor coupled to the first and second parameter memory banks may write parameter data into the inactive one of the first and second parameter memory banks.

The invention relates to the field of semiconductor, more particularly, to a preparation process of image sensors, comprising: Step S1, providing a semiconductor structure, a top of which is provided with a groove, and leads being formed in said groove, the top of said semiconductor structure and an exposed surface of said groove are covered with a first dielectric layer; Step S2: depositing a second dielectric layer covering the upper surface of said first dielectric layer and said leads and filling said groove; Step S3: performing a reversed-etching process to thin said second dielectric layer, and to form a convex structure on a surface of said second dielectric layer above the groove; Step S4: performing a planarization process to said second dielectric layer to improve surface evenness of said second dielectric layer after grinding by the convex structure.
摘要:
A fitting for vacuum assisted resin transfer molding and an associated method of use. The fitting includes a base, a sealing washer, a sealing nut, and an inner nut. The fitting is adapted such that it may be reused many times without failing and without causing damage to the fitting, the mold or any resulting hardened resin.

There is disclosed a wireless communications system, a method for wireless communication, and an omnibus access point. The omnibus access point may receive, from a user device, a request to join an identified service set. The omnibus access point may attempt to identify an access point associated with the identified service set. When the omnibus access point identifies the access point associated with the identified service set, the omnibus access point may establish a communications path between the omnibus access point and the identified access point to allow communications between the user device and the identified service set.
摘要:
Systems and methods for a device connected to a private network to efficiently retrieve a software/firmware update. The device may retrieve an update scheme that defines an external Uniform Resource Identifier (URI) for a resource external to the private network and a primary URI for a primary resource connected to the private network. The device may compare own Internet Protocol address and the primary URI to determine whether or not the device is the primary resource. When the device is the primary resource, the device may retrieve the software/firmware update from the external URI.
摘要:
An adaptive AC power exchanger generates stable 120 VAC 60 Hz power from variable grid input power nominally at 220 VAC and 50 Hz. The exchanger includes an AC-DC circuit stage coupled to receive the input AC current and generate a VDC output, and a DC-AC circuit stage to generate power for a load. The AC-DC stage includes an EMI filter and surge protection circuit, a 50 Hz rectifier and a power factor correction (PFC) circuit controlled by a PFC controller to yield a 400 VDC output coupled through a bulk capacitor stack to a common connection to generate a 200 VDC voltage node. The 200 VDC and 400 VDC voltages are coupled to the DC-AC circuit including a pulse width modulator; current load limiter; an LC filter having a capacitor, dual inductors and an inductor by-pass relay; and a load disconnect relay all controlled by an AC bridge controller.
