Abstract: Provided is an apparatus and a method thereof which can detect a displacement amount of a cutting tool with respect to a workpiece with high accuracy and can correct a processing position with high accuracy. Accordingly, a turret gauge 46 is comprised of an invar body 47 and a gauge main body 48 with a different thermal expansion coefficient. A point A of the gauge main body 48 and a leading edge 47A of the invar body are imaged in a state of viewing the whole thereof at a time of an initialization and a calibration cycle (CS), and a temperature of the gauge main body 48 is detected by comparing each image data. Furthermore, the length between the point A and a point B of the gauge main body 48 at the time of the CS is obtained based on the image data. The actual length is compared with a theoretical length between the point A and the point B at a temperature of the gauge main body 48 at the time of the CS, and consideration is given to the comparison.

Abstract: A picture (1) with multiple slices (2-5) is encoded by determining a hierarchical granularity for the picture (1) defining a hierarchical level for slice border alignments. Address information allowing identification for a respective slice start is determined for at least a portion of the slices (2-5) based on the hierarchical granularity. The pixel values of the slices are encoded to generate coded slice representations (56). These coded slice representations (56) are included together with the address information into a coded picture representation (50) to which information of the hierarchical granularity is associated. The hierarchical granularity provides a flexible way of defining at which coding unit level slice borders can be present in the picture (1).

Abstract: A picture (1) with multiple slices (2-5) is encoded by generating a coded slice representation for each of the slices. A slice flag is set to a first value for the first slice (2) in the picture (1) and corresponding slice flags of the remaining slices (3-5) are set to a second defined value. A respective slice address is generated for each remaining slice (3-5) to enable identification of the slice start position within the picture (1) for the slice. A coded picture representation (50) of the picture (1) comprises the coded slice representations, the slice addresses and the slice flags. The slice flags enable differentiation between slices (3-5) for which slice addresses are required and the slice (2) per picture (1) for which no slice address is needed to identify its slice start position.

Abstract: A method comprising: for each target image portion to be encoded in a frame, selecting one of a set of encoding modes by optimizing a function comprising an estimate of distortion for the target image portion and a measure of bit rate required to encode the target image portion, encoding the target image portion into the encoded video stream using the selected mode. The encoded video stream is transmitted over a lossy channel. An error propagation distortion map is maintained, which comprises a plurality of error propagation distortion values mapping to respective frame partitions, the error propagation distortion values being based on previous encoding mode selections. The estimate of distortion used to select the encoding mode for each of the target image portions is based on a corresponding portion from the error propagation distortion map, and that corresponding portion is constrained to being co-located with the target image portion.

Abstract: A power mode designating unit of a main system outputs an operation mode designating signal to a sub system. Upon shifting from the normal operation mode to the power-saving mode, a control unit of the sub system outputs a power-saving mode shift enable signal indicating that shifting to the power-saving mode is possible to a power control unit of the sub system. When the operation mode designating signal designates the power-saving mode and the power-saving mode shift enable signal indicates that shifting to the power-saving mode is possible, the power control unit supplies a power-saving mode voltage to the control unit.

Abstract: Embodiments of a synchronization circuit, a method for synchronizing clock signals, and electronic devices that include the synchronization circuit or a computer-program product (e.g., software) with instructions for operations in the method are described. This synchronization circuit synchronizes clock signals in different timing domains using state variables. In particular, the synchronization circuit generates a synchronization acquisition curve based on a temporal history of state-variable differences between the clock signals. Next, the synchronization circuit synchronizes the clock signals (without a discontinuous temporal transient in one or more state variables of a dependent one of the clock signals) based on the sum of the synchronization acquisition curve and the state-variable differences between the clock signals.

Abstract: A Power-over-Ethernet (PoE) communication system dynamically provides power and data communications over a communications link. In a computing environment made up of one or more personal computing devices (PCD) and/or one or more powered devices (PD), power source equipment (PSE) determines an allocated amount of power to be supplied to each device. The personal computing devices include a unified LAN-On-Motherboard (LOM) that combines the functionality of a powered device (PD) controller of a conventional PD and a LOM of a conventional personal computing device into a single unified subsystem. The unified LOM includes a standard or universal interface between the LOM and PD controller so that different types of PD devices with differing functionality can be easily married to the LOM, without requiring significant hardware or software redesign.
