Title: Method and apparatus for performing analog mode operations when receiving data and signaling tones in a wireless tdma system
Inventor: LEONARD ERIC DAVID
IPC: H04L7/04
Filed: 2001-01-23
Abstract: A method and apparatus are provided for use in a transceiver of a wireless system that enable analog mode operations to be performed using in-phase (I) and quadrature (Q) values. When operating in the analog mode, the apparatus comprises a processor that receives digital I, Q pairs relating to audio or data signals and performs FM  demodulation to generate information content relating to the audio or data signals. When receiving data in the analog mode, the data is in a particular format. In order to decode the data, the processor looks at each bit of the data for five repeats of Radio Link Words (RLWs) and generates and stores a confidence factor associated with each bit. The confidence factor is based on how closely the waveform represents a 1 or a 0 as well as the signal strength. If the waveform has relatively little noise and if the RF signal strength is relatively high, the processor assigns more weight to its determination as to whether the waveform represents a 1 or a 0. Once this process has been performed for each repeat of the current RLW, the processor takes the sum of the confidence factors associated with each bit and compares the sum to a threshold level to determine whether the bit is a 1 or a 0. A  signaling tone detection routine is utilized to distinguish between when data is being received and when signaling tone is being received.

Inventor: SALLAM HUSSEIN
IPC: G06F3/00
Filed: 2001-04-12
Abstract: The invention is essentially a novel computer architecture which is absent the traditional parallel system bus. The computer makes use of a serial bus controller (SBC) and serial communication lines to facilitate communication between attached system components and any peripheral devices. The components themselves can be in their own enclosures, designed to and will contain BIOS-type information sufficient to characterize themselves and convey any necessary protocol for communicating with themselves. At each system boot different system components such as CPU(s), memory modules, fixed disks, etc. can be added or removed and even while in the powered on state various peripheral devices can be added and removed. This architecture permits infinite combinations of system configurations limited only by the number of available connections to the serial bus controller.  Individual components are interconnected via high speed serial data transmission and thus are not subject to the distance limitations imposed by the inherent properties of the parallel system bus.

Abstract: A vacuum dry sprinkler system includes a sprinkler head formed with a body having a central orifice through which fire extinguishing fluid is expelled through an outlet end. A yoke, attached to the exterior surface of the sprinkler body, extends beyond the outlet end of the sprinkler body and is connected at its apex to a deflector. A thermally sensitive trigger member is coupled to the yoke and the outlet end of the sprinkler head. The sprinkler body carries an expulsion assembly which includes an expulsion member and a thrust member. In response to a fire, the expulsion member of the expulsion assembly overcomes the vacuum force and expels the sealing assembly out of the outlet end of the sprinkler body, while the thrust member laterally thrusts the sealing member out of the water trajectory path, and thus, prevents the sealing assembly from reseating on the outlet of the sprinkler head.

Patent CA-2367274-A1 (CA)
Inventor: GILL WALTER S
IPC: B65D5/34
Filed: 2002-01-08
Abstract: Exhibiting favorable attributes of both a regular slotted container ("RSC") and an automatic bottom container, a sheet material container is quickly and easily erectable from a knocked-down-flat ("KDF") container precursor. The precursor collapses to a uniform two-layer KDF condition which permits stable, even stacking of multiple precursors for bulk shipping and storage of the same. The precursor is formed from a blank including a plurality of wall panels hingedly attached to each other along fold lines to form a closed loop of wall panels, and a plurality of end flap panels hingedly attached along fold lines to ends of the respective wall panels. A pair of adjacent end flap panels lie in face-to-face relation with each other in the KDF condition. One of the adjacent pairs of panels has a diagonal fold line defining a corner attachment region that attaches to the other end flap panel. As the closed loop of wall panels is erected from the KDF condition to form a rectangular tubular shape, the diagonal fold line and associated attachment of end flap panels cause the end flap panels to pivot inwardly to automatically form an end closure (e.g., bottom) surface of the container.
