Abstract: A storage array uses paged metadata. Each storage director has access to a plurality of object storage systems which describe locations of paged metadata in backing storage. Each object storage system includes different types of inodes which describe objects in backing storage. The object storage systems are used to locate and relocate metadata for loading into global memory, and creation and deletion of objects. An object storage system may be selected based on factors including ratio of different inode types, locality of object usage and anticipated object activity level.

Abstract: A semiconductor device includes a substrate, an integrated passive device (IPD). and a phase-change material (PCM) radio frequency (RF) switch. The PCM RF switch includes a heating element, a PCM situated over the heating element, and PCM contacts situated over passive segments of the PCM. The heating element extends transverse to the PCM, with a heater line underlying an active segment of the PCM. The PCM RF switch is situated over a heat spreader that is situated over the substrate. The heat spreader and/or the substrate dissipate heat generated by the heating element and reduce RF noise coupling between the PCM RF switch and the IPD. An electrically insulating layer can be situated between the heat spreader and the substrate. In another approach, the PCM RF switch is situated over an RF isolation region that allows the substrate to dissipate heat and that reduces RF noise coupling.

Abstract: The quantization parameters (QP) for Chroma are extended up to and more preferably to the same range as Luma QP (e.g., 0 to 51). Previous, values of Chroma QP only extended up to 39. Techniques are provided for determining extended Chroma QP values (e.g., for Cr and Cb) based on the Luma QP and picture level chroma offsets. In one preferred embodiment, slice level offsets are added making the method particularly well-suited for slice level parallel processing. The extension of Chroma QP enhances functionality, flexibility and friendliness of the High Efficiency Video Coding (HEVC) standard for various applications.

Abstract: An apparatus is provided for using a square wave digital chirp signal for optical chirp range detection. A laser source emits an optical signal and a RF waveform generator generates an input digital chirp signal based on the square wave digital chirp signal. A frequency of the optical signal is modulated based on the input digital chirp signal. A splitter divides the optical signal into a transmit optical signal and a reference optical signal. A detector combines the reference optical signal and a return optical signal from an object. The detector generates an electrical output signal based on the combined reference optical signal and the return optical signal. A processor determines a range to the object based on a characteristic of a Fourier transform the electrical output signal. A method is also provided for using the square wave digital chirp signal for optical chirp range detection.

Abstract: Described herein are devices, systems and methods for accessing devices, such as modules or printed circuit boards (PCBs), for electrical communications. Various connectors described herein utilize a side-edge surface of a device, such as a PCB, for connectivity in order to maximize the surface area on the PCB upon which electronic components can be mounted. Such connectors can be used to temporarily connect to devices (e.g., PCBs) for the purposes of debugging, testing and/or configuring circuitry, firmware and/or software. Each such connector utilizes the side-edge surface of a device along its thickness to provide connectivity, which is useful in many situations, including when the device (e.g., a PCB) is to be soldered as a part onto a larger board at a later point in time, or where multiple PCBs are stacked.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for monitoring energy consumption. In one aspect, a method includes sending, to a power monitor of a circuit board, requests for power consumption data. The requests are sent periodically based on a reference clock that is located external to the circuit board and that is more accurate than a clock of the power monitor. Each request is for an accumulated amount of power for components of the circuit board. In response to each request, power consumption data is received from the power monitor. The power consumption data specifies the accumulated amount of power for the components of the circuit board since a previous request sent to the circuit board. An amount of energy consumed by the components of the circuit board over a time period is determined based on the received power measurements and the time period.

That scanner provides corresponding identifying information regarding that returning product to a control circuit that in turn uses that information to automatically process an exchange transaction of the returning product for a substitute product in the product display area such that the exchange transaction occurs without the customer engaging either the customer service area or one of the POS stations.

Abstract: Embodiments relate to efficiently replicating data from a source storage space to a target storage space. The storage spaces share a common namespace of paths where content units are stored. A shallow cache is maintained for the target storage space. Each entry in the cache includes a hash of a content unit in the target storage space and associated hierarchy paths in the target storage space where the corresponding content unit is stored. When a set of content units in the source storage space is to be replicated at the target storage space, any content unit with a hash in the cache is replicated from one of the associated paths in the cache, thus avoiding having to replicate content from the source storage space.
