Abstract: A pad shape for a support assembly is optimized to provide universal fitting characteristics to Head-Mounted Display (HMD) devices. The pad shape enables a display of a single HMD device to be reliably aligned within multiple users' fields-of-view notwithstanding significant variations of shape and size between these users' heads. Optimal positioning of the display within the multiple users' fields-of-view may be achieved by positionally constraining the HMD device against a portion of the head that varies relatively slightly as compared to other portions of the head. The contact pad includes a curved region having a shape defined by a high order polynomial that corresponds to an empirically determined best fit surface. Empirically determining one or both of the best fit surface or the high order polynomial may include aligning a plurality of “forehead” point clouds that map the geometries of a sample set of users' foreheads.

Abstract: A sensor data processing system of an autonomous vehicle can receive inertial measurement unit (IMU) data from one or more IMUs of the autonomous vehicle. Based at least in part on the IMU data, the system can identify an IMU data offset from a deficient IMU of the one or more IMUs, and generate an offset compensation transform to compensate for the IMU data offset from the deficient IMU. The system may then dynamically execute the offset compensation transform on the IMU data from the deficient IMU to dynamically compensate for the IMU data offset.

Abstract: An HMD adjusts adjusting depth information based on detected motion of the system. The HMD includes a depth camera that collects depth data for objects in the local environment of the HMD. The HMD further includes an inertial measurement unit (IMU) including non-visual motion sensors such as one or more accelerometers, gyroscopes, and the like. The HMD adjusts the received depth information based on motion data provided by the IMU, thereby improving the accuracy of the depth information, and in turn reducing visual artifacts that can result from inaccuracies in the depth information.

Abstract: A system and method for cutting tissue within a synovial cavity, which includes a cannula and a blade assembly. The cannula can define an internal lumen and a cutting port for accessing the internal lumen. The blade assembly can include a blade and a blade shall extending from the blade. The blade can be inserted into the internal lumen of the cannula through an access port of the cannula such that the blade is proximate the cutting port.

Abstract: A secure one-way network gateway for transmitting data from a source network to a destination network is disclosed. An input circuit is for coupling to a source network and an output circuit is for coupling to an output network. A memory stores configuration data. Either a single field-programmable device or a pair of field-programmable devices coupled via a one-way link are inserted between the input circuit and the output circuit. The configuration data is loaded into the device(s) to program the device(s) to pass data from the input circuit to the output circuit, to optionally filter the data, and to prevent any data from passing from the output circuit to the input circuit. A processor is coupled to only the memory and a separate management interface. The processor receives updated configuration data via the management interface and replaces the configuration data in the memory with the updated configuration memory.

Abstract: A circuit provides for regulating charge and discharge current of a battery. A bypass circuit is connected to a terminal of the battery and connected in parallel with a load switch. The bypass circuit may selectively direct a bypass current around the load switch. A controller can operate in plural modes to control the bypass circuit. In a first mode, the controller controls one or more parameters of the bypass current based on values corresponding to a current at the terminal, a voltage at the terminal, and/or a temperature of the battery. In a second mode, the controller controls the bypass circuit to disable the bypass current.

Abstract: Methods and apparatus for a Secure Time Communication System (10) are disclosed. One embodiment of the invention provides secure and non-interactive communication of clock information over an unsecured communications channel. This communication provides perfect forward secrecy, while detecting and blocking message spoofing, message replay, denial of service and cryptographic performance attacks. This mechanism also bounds the effect of message delay manipulation. The mechanism consists of two components, a filtered time encryptor (16) and a filtered time decryptor (28). The filtered time encryptor (16) produces a message in two parts; a time token followed by an encrypted message body. The time token is used as a filter to detect most attacks and to determine the message key.
