摘要： An apparatus comprising a first circuit and a circuit. The first circuit may be configured to receive an input signal, split the input signal into component signals and present the component signals to a plurality of amplifiers. The second circuit may be configured to receive amplified component signals from the amplifiers and combine the amplified component signals into an output signal. The circuits may each comprise an outer conductor, an inner conductor, a cavity and a plurality of blades. Each of the blades may be arranged evenly spaced along a surface within the cavity and extend along a length of the surface with a shape. The shape of the blades may have a probe and the shape may gradually meet the surface and may be configured to provide a low-loss transition for propagation of a microwave signal. The output signal may be an amplified version of said input signal.

摘要： An apparatus comprising a first light source, a second light source, a controller and a power source. The first light source may activate color channels of a reactive material in response to a signal. The second light source may deactivate a subset of the color channels of the reactive material in response to the signal. The controller may receive an input, determine characteristics for the light sources in response to the input and generate the signal in response to the first characteristics and the second characteristics. The power source may provide power for the light sources and the controller. The reactive material may change appearance in response to the subset of the color channels deactivated. The power source and the controller may be contained in a housing of the apparatus. The light sources may enable the apparatus to emit light onto an object comprising the reactive material.

摘要： A system comprising a capture device and a database. The capture device may be configured to (i) capture video, (ii) perform video analysis to extract metadata corresponding to the captured video and (iii) communicate with a wireless communication device. The database may be configured to (i) communicate with the wireless communication device, (ii) store the metadata received from the wireless communication device, (iii) generate search results for a user based on the metadata and (iv) provide the user at least one of (a) the metadata and (b) the captured video based on the search results. The metadata may be used to determine license plates present in the captured video. The capture device may transmit the captured video to the database via the wireless communication device based on a request by the user.

摘要： An apparatus including an interface and a processor. The interface may be configured to receive pixel data of an area external to a vehicle. The processor may be configured to generate video frames from the pixel data, perform computer vision operations on the video frames to detect objects in the video frames and determine characteristics of the objects, analyze the characteristics of the objects to determine a visually observable status of the objects, perform a comparison of the visually observable status to a remote command and send the remote command if the comparison determines that the visually observable status does not match the remote command. The remote command may be configured to control the visually observable status of the objects.

摘要： An apparatus comprises a cross-coupled differential amplifier, an inductive-capacitive (LC) tank circuit, and a low-noise voltage supply. The inductive-capacitive (LC) tank circuit is generally coupled in a feedback path of the cross-coupled differential amplifier. The LC tank circuit generally comprises (i) an inductance provided by an inductor, (ii) a first capacitance provided by a parallel coupled varactor circuit, (iii) a second capacitance provided by a parallel coupled first switched-capacitor bank, and (iv) a third capacitance provided by a parallel coupled second switched-capacitor bank. The low-noise voltage supply may be configured to provide a supply voltage of the cross-coupled differential amplifier. The parallel coupled varactor circuit comprises a pair of thick oxide varactors connected with a reverse varactor connection. The parallel coupled first switched-capacitor bank and the parallel coupled second switched-capacitor bank comprise thin oxide switches.

摘要： The invention concerns a system comprising a security device and a computing device. The security device may be configured to generate first video frames at a first bitrate and second video frames at a second bitrate from pixel data, store the video frames and metadata comprising index information for the video frames, communicate the second video frames and the metadata. The computing device may be configured to receive a video selection and a command from a user via an interface, display the second video frames using the interface in response to the video selection and communicate the command to the security device. The command may enable a modification to the first video frames stored on the security device using the display of the second video frames on the interface based on the metadata. The security device may generate modified first video frames in response to the command.
