Title: High speed encoder and encoding method
Inventor: TOWNSHEND BRENT
IPC: H04L25/49
Filed: 1995-12-04
Granted: 2002-04-02
Abstract: A new data communication system is described which enables data transmission over existing telephone lines at rates higher than possible with existing methods, including conventional modems. By using a novel asymmetric configuration of the two communicator endpoints, the currently-accepted maximum theoretical limits on the data rate are no longer applicable. One endpoint is connected directly to a digital telephone network, whereas the other endpoint uses a conventional telephone connection. This reduces the transmission problem to compensation for a single telephone line interface and a single analog local loop. Means of providing this compensation and the required clock synchronization were also created, enabling a practical, implementation of the system.      The new system can achieve rates up to 64,000 bits-per-second and has broad utility in several active areas including wide-band audio transmission, video transmission, networking, facsimile transmission, and remote computer access.

Abstract: An eight-bit RISC based microcontroller (Fig. 1) includes an eight-bit register file (20) having a dedicated arithmetic logic unit (ALU2), i n addition to a general purpose eight-bit ALU (22). The register file further includes means for combining (16) a pair of registers to provide a logical sixteen-bit register for indirect addressing. The dedicated ALU is a sixteen - bit ALU which provides certain arithmetic functions for the register pair, thus alleviating the computational burdens that would otherwise be imposed o n the general purpose eight-bit ALU. A further feature of the invention is the  inclusion of a paging register (RAMP x, y, z) which is combined with the contents (14') of the logical sixteen-bit register to provided an even great er addressing range. Yet another feature of the eight-bit microcontroller of th e present invention is the means (134) for directly reading and writing to any  bit position within the register file with a single instruction. This avoids  having to perform various load, shift and/or masking operations needed by prior art microcontrollers.

This method effectively controls biofouling without substantially killing the fouling organisms. The amino methyl phosphonic acid used in the methods of the invention has the formula R1R2NCH2P(O)(OH)2. In this formula, R1 and R2 are independently a C6-C20 alkyl group or a CH2P(O)(OH)2 group.  However, R1 and R2 are not both a CH2 P(O)(OH)2 group.  Alternatively, R1 and R2, together with the N, may also form a 5-8 membered heterocyclic ring having formula (a). In the heterocyclic ring, X is O, NH, or CH2. The salt of an amino methyl phosphonic acid can be an acid salt or a quaternized amino methyl phosphonic acid salt. The invention also relates to a composition containing amino methyl phosphonic acids or salts thereof and useable in the above methods. The compositions comprise at least one amino methyl phosphonic acid or salt thereof in an amount effective to inhibit bacteria from adhering to submergible or submerged surfaces.

Granted: 2008-12-16
Abstract: An automated slide stainer with slides mounted in a horizontal position on a rotary carousel. Reagents and rinse liquids are automatically dispensed onto tissue sections or cells mounted on slides for the purpose of performing chemical or immunohistochemical stains. The rinse liquids are removed by an aspiration head (31) connected to a source of vacuum. The aspiration head (31) is a hollow chamber (40) with a flattened bottom aspect. Eight holes (41) in the bottom of the aspiration head provide for fluid communication between the exterior and interior of the aspiration head. To aspirate liquid off of a slide, the aspiration head is lowered so that the bottom aspect contacts the liquid. The liquid is sucked into the hollow interior (40) of the aspiration head and collected into a liquid waste collection bottle. Several different liquid waste collection bottles (59) are placed in parallel, between the source of vacuum and the aspiration head.  A solenoid valve (80) is positioned in line with each liquid waste collection bottle. Depending upon which solenoid valve is opened, the operator can direct the liquid waste to be collected into a specified liquid waste collection bottle.

Granted: 2004-03-23
Abstract: The system for providing calling party privacy during subscriber call screening for a central office switching system enables a subscriber to monitor and intercept the last forwarded, active call to the Voice Messaging System, while providing the calling party with privacy as the voice messaging system provides the prerecorded instructions/message to the calling party. The calling party privacy feature delays call screening alerting to the subscriber to prevent the subscriber from monitoring the call connection until the calling party is recording their message on the voice messaging system. Depending on the method used, once the calling party privacy feature requirements. are satisfied, the subscriber call screening system notifies the subscriber of the presence of a calling party who is recording a message for the subscriber on the Voice Messaging System.
