Abstract: A wearable display system includes a light projection system having one or more emissive microdisplays, e.g., micro-LED displays. The light projection system projects time-multiplexed left-eye and right-eye images, which pass through an optical router having a polarizer and a switchable polarization rotator. The optical router is synchronized with the generation of images by the light projection system to impart a first polarization to left-eye images and a second different polarization to right-eye images. Light of the first polarization is incoupled into an eyepiece having one or more waveguides for outputting light to one of the left and right eyes, while light of the second polarization may be incoupled into another eyepiece having one or more waveguides for outputting light to the other of the left and right eyes. Each eyepiece may output incoupled light with variable amounts of wavefront divergence, to elicit different accommodation responses from the user's eyes.

Abstract: Methods, systems, and apparatuses include evaluating a possibility of having more than a threshold number of connections with an access point of a network at a same time by multiple IoT devices that access the server through the network. In response to the evaluation, a determination of schedules for IoT devices is performed such that when the IoT devices operate according to the schedules the connections with the access point by the IoT devices that occur at the same time do not exceed the threshold number of connections. Configuration parameters are transmitted to the IoT devices causing the IoT devices to operate according to the schedules.

Abstract: This disclosure describes techniques for interoperability of a blade server in a server chassis, where IOMs of the server chassis do not provide dedicated pins for communicating a physical slot ID to the blade server. BMCs of the blade servers and CMCs of IOMs of the server chassis are mutually configured to broadcast Ethernet frames on layer 2 network segments over a broadcast domain configured by a switch module connected to the blade servers over layer 2 network segments; conduct a slot inference communication protocol using these Ethernet frame broadcasts to enable the CMC to determine a physical slot ID in response to a BMC request, and broadcast that physical slot ID back to the BMC; and use a public certificate-private certificate pair, based in a hardware root of trust, to enforce security of this communication protocol.

Abstract: A system receives vehicle metric data from a gateway device connected to a vehicle via a network connection. In a first power mode, the vehicle gateway device gathers vehicle metric data related to operation of the vehicle and/or location data and sends requested vehicle metric data to the system. Based on a lack of input, the vehicle gateway device enters a standby power mode to reduce the power consumption of the vehicle gateway device. The vehicle gateway device reduces the power consumption by reducing activity of the vehicle gateway device. Instead of reinitiating a network connection periodically to receive requests for vehicle metric data from the system, the vehicle gateway device maintains the network connection by sending keep alive messages between the vehicle gateway device and the system. The system uses the maintained network connection to request vehicle metric data.

Abstract: A method and a gateway system of a mobile asset are described. A voltage produced by a power system of the mobile asset is monitored by a gateway system. In response to determining that a first fluctuation occurs in the voltage produced by the power system of the mobile asset over a first interval of time, the gateway system operates in a first mode. In response to determining that a value of the voltage produced by the power system of the mobile asset is less than a voltage threshold, the gateway system automatically transitions to operating in a second mode, which is different from the first mode and causes the gateway system to consume less power than when it is operating in the first mode.
