Title: Master and slave communications with multiple message frame sent over long link and broken into multiple single message frames sent over short links
Inventor: MANZARDO MARCEL B
IPC: H04L29/06
Filed: 2000-04-26
Abstract: A method and a system for improving the exchange of data between a master system 72 and multiple slave systems 78, 80, 82, and 84 involves bundling multiple abbreviated messages into a single frame and transmitting the single frame across a long delay communications link 94. The abbreviated messages do not comply with a given transmission protocol such as high-level data link control HDLC, while the single frame does comply with the transmission protocol. The abbreviated messages are then used to build multiple protocol-compliant frames that are sequentially transmitted across short delay communications links. By bundling multiple abbreviated messages into a single frame, the number of frame transmissions required across the long delay communications link is minimized, while the sequential transmission of protocol-compliant frames to and from the slave systems is accomplished. The master system may be a main PBX and the slaves line cards.

Title: Sensorless control system for induction motor
Inventor: PAVLOV ALEXEY
IPC: H02P21/14
Filed: 2002-03-18
Abstract: A sensorless control system for an induction motor 10 employs direct tracking of torque and flux regulation to achieve improved motor control without the need for transformation to the rotor flux related frame. A novel torque-flux dynamic model used to implement the control method employs stator voltage as an input, and achieves separation of torque and flux regulation. An alternative regulation method better suited for slow reference signals relies on a steady state solution of the dynamic model. Measured stator current signals i<SB>sa</SB>, i<SB>sb</SB>, i<SB>sc</SB> are used together with stator voltage commands u<SB>x</SB>, u<SB>y</SB> to calculate speed, flux and torque of the motor. Flux and torque signals are compared with reference signals F<SB>ref</SB>, T<SB>ref</SB> to calculate the voltage command signals.

Title: Radiation emitter
Inventor: COLE BRYAN EDWARD
IPC: H01S1/02
Filed: 2002-09-04
Abstract: A terahertz radiation emitter, where a bias is applied between two contact assemblies 12, 13, 14 facing one another and separated by photoconducting semiconductor material 11. Transient currents excited by sub-picosecond laser pulses cause emission of radiation over a band dependent on the photoconductor carrier lifetime. At least one resistive element 14 integrated on the photoconductive substrate restricts current flow between the contacts at frequencies lower than the desired emitting range, decreasing power dissipation of the device. The contacts can form a simple dipole antenna or a bow-tie antenna, edges of the elements adjacent the photoconducting gap comprising antenna electrodes. In some embodiments a dielectric film is disposed over the surface of the device (figs 2 & 3) filling the gap between antenna electrodes to suppress electrical breakdown. Other embodiments provide methods of determining an optimal resistive value for use as a series biasing resistance in a terhertz emitter, based on laser repetition frequency and device capacitance.
