Title: System for allowing i/o processor to operate under different transfer algorithms
Inventor: ANDO WAYNE
IPC: G06F13/28
Filed: 1997-07-24
Granted: 2001-09-25
Abstract: A programmable DMA controller (110) that uses an instruction set dedicated t o moving data efficiently over a bus (108), comprising a program memory (228),  a program counter (226), a FIFO memory (222), a bus buffer (224), registers, a n accumulator, and an ALU (220). The DMA controller instruction set comprises the following instructions: load, move, add, subtract, branch on zero, branc h on not zero, lock, and interrupt. Another DMA controller embodiment uses a SIMD processor. In operation, a CPU downloads DMA programs to the DMA controller. The DMA controller stores these programs in its program memory. The CPU signals the DMA to begin a DMA transfer operation. The ALU and associated devices execute the program instructions to perform the desired D MA transfer. The DMA controller then sends an interrupt to the CPU to indicate the DMA transfer is complete.

Abstract: A machine is disclosed for conveying wooden piece such as logs of wood and lumber, in wood transformation industries such as sawmills. The wooden pieces are conveyed in a conveying direction from the front towards the back of the frame of the machine. The machine has several conveying shafts rotatably mounted in parallel on the sides of the frame. Each shaft has a rotating axis about which it is driven in rotation in a direction corresponding to the conveying direction. Several toothed circular plates are mounted on each shaft and extend in a plane crossing the axis of rotation of the shafts. The plates of a shaft are designed to be offset with respect to the plates of an adjacent shaft. Each tooth of each plate are spaced apart from an adjacent tooth by a distance which corresponds substantially to the range of diameter of the wooden pieces and defines a space therebetween for receiving at least a portion of a wooden piece. The teeth of the plates mounted on a same shaft disposed in order to be aligned together. In action, the rotation of the conveying shafts are synchronised together in such a way that a wooden piece inserted between two teeth of the conveying plates of a shaft is conveyed in the direction of rotation of this shaft until a tooth of the plates of an adjacent downstream shaft carries the wooden piece. So the wooden piece is transferred to the adjacent shaft and is engaged and carried between two teeth of the plates of the adjacent shaft. Therefore, the adjacent downstream shaft conveys the wooden piece further with respect to the conveying direction. The machine can be designed in order to convey the wooden pieces horizontally or upwardly.

Title: Practical space-time radio method for cdma communication capacity enhancement
Inventor: SCHERZER SHIMON B
IPC: H04B7/04
Filed: 1998-09-15
Granted: 2005-06-14
Abstract: A practical way to enhance signal quality (carrier to interference, C/I) in both up and downlink of wireless point to multi-point CDMA service implements basic radio direction finding techniques to allow for optimal diversity combining in an antenna array employing large number of elements. This approach is facilitated through the use of very small bit counts arithmetic and capitalizing on finite alphabet signal structure (Walsh symbols, for example in IS-95 CDMA) or a known training sequence. Alternate implementations can use floating point data representations. The method facilitates ASIC implementation, thereby enabling distributed processing to achieve the required computation practicality. The method utilizes the uplink channel data to determine the downlink spatial structure (array beams) to enhance downlink G/I and hence increase downlink capacity. The preferred embodiment is optimized to IS-95, however any signal that has either a finite alphabet or a training sequence built in can utilize the same idea. The use of the known signal structure facilitates simple array response vector determination and eliminates the necessity for covariance matrix calculation and analysis. Hence, this approach can be utilized for GSM and TDMA wireless air-interfaces as well.

Abstract: Coordination of processing satellite uplink transmission and downlink transmission is achieved by an uplink encoder (418) and uplink modulator (420) which incorporate an adjustable IF amplifier (417) at a ground terminal (400).      Information about data traffic transmission errors detected in a satellite (100) is formed into ATM traffic report cells by a cell former (157). The traffic report cells are sent on the downlink to the ground terminal. The traffic report cells are used to adjust the power level of the IF amplifier for the particular channel and slot for which errors were detected.      Satellite 100 also detects the time of arrival of a synchronization burst signal at the satellite and estimates the received energy in the burst signal. Another cell former (144) forms ATM synchronization report cells, including information about the arrival time and energy, which are sent on the downlink to the ground terminal. The synchronization report cells are used to adjust the power of the IF amplifier for all channels and to adjust the time at which frames are transmitted on the uplink.

Title: Frac plug with caged ball
Inventor: VARGUS GREGORY W
IPC: E21B11/04

Granted: 2009-06-02
Abstract: A downhole tool for sealing a wellbore. The downhole tool includes a packer with a ball seat defined therein. A sealing ball is carried with the packer into the well. The movement of the sealing ball away from the ball seat is limited by a ball cage which is attached to the upper end of the packer. The ball cage has a plurality of ports therethrough for allowing flow into the ball cage and through the packer at certain flow rates. A spring is disposed in a longitudinal opening of the packer and engages the sealing ball to prevent the sealing ball from engaging the ball seat until a predetermined flow rate is reached. When the packer is set in the hole, flow through the frac plug below a predetermined flow rate is permitted. Once a predetermined flow rate in the well is reached, a spring force of the spring will be overcome and the sealing ball will engage the ball seat so that no flow through the frac plug is permitted.
