Patent CA-2276198-A1 (CA)
Inventor: THANAWALA ASHISH A
IPC: H04J3/02
Filed: 1995-04-18
Abstract: A data multiplexing network is described which multiplexes a plurality of asynchronous data channels with an asynchronous data stream representing compressed voice signals and/or facsimile signals onto a single synchronous data packet stream. The single synchronous data packet stream is then transmitted by a high speed statistical multiplexer over a composite link to a second site using a modified high-level synchronous data link control protocol with an overlay of an advanced priority statistical multiplexing algorithm. The asynchronous data channels and the compressed voice channel and/or facsimile signals are demultiplexed and reconstructed for sending to other asynchronous computer terminals and to a standard telephone or facsimile analog port at the second site, respectively. PBX trunk interfaces are also provided to allow PBX's to share the composite link between sites. Communication between the first site by voice or facsimile and the second site is transparent to the users. The multiplexer efficiently allocates the bandwidth of the composite link by detecting silence periods in the voice signals and suppressing the sending of the voice information to preserve bandwidth. An advanced priority statistical multiplexer is also described which dynamically allocates composite link bandwidth to both time-sensitive and non-time-sensitive data to maximize data throughout efficiency and quality while simultaneously reducing multiplexer processing overhead.

Title: Cooling device with waterproof structure
Inventor: OKAMOTO YOSHIYUKI
IPC: H05K7/20
Filed: 2000-09-14
Abstract: A cooling device for cooling an inner part of an approximately sealed box includes a casing and a heat exchanger disposed in the casing. Plural inside air passages through which air inside the box flows and plural outside air passages through which air outside the box flows are alternately adjacently arranged in the heat exchanger. In the cooling device, both outside air introduction port and outside air discharge port are provided in an outer side plate of the casing, and a drain space is provided between the heat exchanger and the outer side plate of the casing so that outside air passages communicate with the outside air discharge port through the drain space.

Patent CA-2319835-A1 (CA)
Inventor: PRESSLEY TODD ALAN
IPC: H04Q7/34
Filed: 1999-02-23
Abstract: A base station transceiver subsystem in a mobile communications environment is configured in the field through a local laptop computer. The computer accesses local management software in the subsystem to input configuration information.  The local manager executes the configuration information without interaction or support of a base station manager connected to the subsystem through the backhaul. Web browser software within the computer facilitates communication with the local manager through TCP/IP or Ethernet interfaces. The subsystem can include a server with configuration scripts that respond to user inputs at the computer. The subsystem is tested, locally, by implementing local calls and/or by tying a loopback line between backhaul ports of the subsystem. A  variety of tests and configurations can thus be made locally, including evaluating backhaul functionality, and without the need for a Base Station Controller and an associated BSM.
