Abstract: Library management for libraries of user-defined routines in a database system. Libraries are stored in a long-term storage device and loaded into working memory in the database system when routines in the libraries are to be executed. An unload thread is defined to carry out the process of unloading libraries from the working memory when such libraries are inactive. The unload thread becomes active on a defined timing interval. The unload thread accesses a hash table and a most recently used list to determine which of the loaded libraries is inactive and which of the libraries ought to be unloaded. The hash table maintains information as to which libraries have been accessed in the most recent past defined timing interval. The size of the most recently used list can be defined such that all libraries associated with the list are retained in working memory.

Title: An optical crosspoint switch using vertically coupled waveguide structure
Inventor: WHITE IAN
IPC: G02F1/365
Filed: 2000-03-30
Granted: 2008-12-16
Abstract: An optical crosspoint switch structure is disclosed. The switch permits light signals to be diverted from any arbitrary number of input ports to any or several of an arbitrary number of output ports. The switch consists of two groups of intercepting optical waveguides formed on a planar substrate, which are the input and output waveguides respectively. At each intersection, another waveguide is formed above the input and output waveguides. Optical coupling between this upper waveguide and the input/output waveguides is controlled by an electrical or optical signal. The upper waveguide has a corner mirror at the intersection. When the control signal allows, light couples from the input waveguide to the upper waveguide. After being reflected by the corner mirror, the light couples from the upper waveguide into the output waveguide. The upper wave-guide incorporates the active switching element. Allowing high modulation depth and low crosstalk level.

Abstract: In a photodetector, a photodiode and a capacitor are coupled between a sensing node and a ground voltage line, and a MOS transistor is coupled between the sensing node and a reference voltage line. Initially, the capacitor is charged so that the sensing node voltage is greater than a transition voltag e and a predetermined gate voltage is applied to switch the transistor off. During a sampling time, the capacitor initially discharges through the photodiode, the dischar ge current being dependent on the intensity of radiation incident on the photodiode, until the sensing node voltage falls to the transition voltage. If the sensing node voltage falls to the transition voltage during the sampling time, the transistor enters it s weak inversion operation domain and the current through the photodiode can flow through the transistor such that the sensing node voltage varies logarithmically wit h the radiation intensity. At the end of the sampling time, a readout circuit coupled to the sensing node generates an output signal dependent on the sensing node voltag e, and the photodetector is reset by recharging the capacitor before the start of another sampling time.

Abstract: A control circuit for an ionizer controls an output of at least one of a positive voltage direct current (DC) power supply (PS) and a negative voltage DC PS.  Each PS is connected to at least one ionizing pin. The control circuit controls the output of the power supplies so as to cause a flow of positive and negative ions from the ionizer and directed towards a target. The control circuit includes a positive PS return current sense resistor that biases the negative voltage PS to decrease the output of the negative voltage PS when the current detected by the positive sense resistor increases and to increase the output of the negative voltage PS when the current detected by the positive sense resistor decreases. The control circuit includes a similar negative PS return current sense resistor and associated bias circuitry for controlling the negative voltage power supply.

Abstract: A method for protecting data recorded on an original storage medium (20) against copying using an unauthorized data readout device. The data are encoded in accordance with Standard 908 of the International Electrotechnical Commission. A portion of the encoded data is altered to introduce a modification in a sub-code Q channel of the data, such that the altered data are inconsistent with an implementation of Standard 908 used in the data readout device, but do not prevent playback of the data following recording thereof. The data, including the altered data, are recorded on the original storage medium, whereby an application which plays back the recorded data runs in a manner substantially unaffected by the alteration of the data, but a substantially unrecoverable error occurs in unauthorized copying of the original storage medium.

Abstract: A variable rate transmission method that can vary the transmission rate of data. A transmitting side supplies a transmitted data sequence to an error detecting encoder 105 and a frame memory 103. The frame memory 103 stores data of a variable length to be transmitted in one frame. The error detecting encoder 105 calculates an error detecting code (such as CRC code) for each frame of the transmitted data. A multiplexer 104 adds the calculated error detecting code ahead of the transmitted data to place it at the initial position of the frame, and sequentially outputs the data sequence frame by frame. A receiving side calculates an error detecting code of the data in each transmitted frame in the same manner as the transmitting side, and compares the calculated error detecting gode with the error detecting code at the initial position of the frame. The end bit of the frame data is decided as a position at which the two error detecting codes coincide. This makes it possible to transmit variable length data without informing the receiving side of the data length in each frame. This is equivalent that the transmission rate can be varied freely.
