Abstract: A nonvolatile storage or memory device is accessed over a memory bus. The memory bus has an electrical interface typically used for volatile memory devices. A controller coupled to the bus sends synchronous data access commands to the nonvolatile memory device, and reads the response from the device bus based on an expected timing of a reply from the nonvolatile memory device. The controller determines the expected timing based on when the command was sent, and characteristics of the nonvolatile memory device. The controller may not need all the electrical signal lines available on the memory bus, and could issue data access commands to different groups of nonvolatile memory devices over different groups of electrical signal lines. The memory bus may be available and configured for either use with a memory controller and volatile memory devices, or a storage controller and nonvolatile memory devices.

Abstract: Described herein are systems, devices, techniques and products for minimizing disruption to network systems due to false detection of a Power over Ethernet (PoE) Power Sourcing Equipment (PSE) as a Powered Device (PD). The disclosed systems, devices, techniques and products provide a way for a PSE to identify itself and avoid being detected as a legacy PD. The disclosed systems, devices, techniques and products further provide a way for a PSE to identify devices that do not require power from the PSE, such as another PSE or a device that is not a PD, and disable automatic PD detection, disable PoE, or otherwise prevent injection of power/current to the other device.

Abstract: The invention relates to an apparatus (1) for powering an electrical consumer (3, 4, 5) via a data connection (6, 7, 8). The apparatus comprises a power supply (2) for supplying power to the electrical consumer via the data connection, a data receiving unit (9) for receiving data to be sent to the electrical consumer, and a controller (10) for activating the supply of power to the electrical consumer via the data connection, if data to be sent to the electrical consumer have been received and the supply of power to the electrical consumer is deactivated. The electrical consumer itself does therefore not need to receive power from the apparatus, in order to stay alert to be able to react on data connection activity, thereby reducing the power consumption.

Abstract: An array of ultrasonic transducers can be controlled to produce a steerable beam. Beam steering can be skewed by buffer delays in the distribution of a clock signal. The skew can be at least approximately linearized by distributing the clock signal in a diagonal fashion across an array of buffers corresponding to ultrasonic transducer controllers. Potential error in beam steering that can arise from clock skew can be corrected based on the linear tilt.

Abstract: A method for efficient battery usage in for portable devices. The method includes a service provider receiving a communication associated with a first device and a second device, wherein one of the first device and the second device is a sender of the communication and the other of the first device and the second device is an intended recipient of the communication.

The service provider may also determine that an emergency communication override feature for the first device has not been enabled. Upon determining that the first mobile device is operating in an energy saving mode and that an emergency communication override feature for the first device has not been enabled, the service provider determines not to send the communication to the intended recipient of the communication.
