Title: Programmable cellular telephone and system
Inventor: SHIRAI KAZUHIKO
IPC: H04W8/26
Filed: 1996-06-04
Abstract: A module (P-code module) provides parameter information to a Number Assignment Module (NAM) in a cellular phone unit by processing a simple programming code (P-code) entered by the user through a telephone keypad. The P-code employs a flexible length telephone keypad coding that can be translated into programmable parameters of cellular phone products. Field identification numbers and look-up tables are used to shorten the P-code length for more frequently used information. To activate a cellular phone, the user provides product and serial number information to a dial- up access center which then generates a scrambled P-code for entry by the user. The P-code module within the processor unit of the cellular phone likewise descrambles, decompresses, and performs an integrity check on the sequence of digits being entered by the user. This P-code module reduces the technical requirements for programming a cellular phone purchased at the retail level such that a user can perform the necessary programming for activating the cellular telephone on a local telephone network. A security arrangement randomly generates two passwords when the cellular telephone is activated to prevent unauthorized reprogramming of the phones for use on other cellular telephone networks.
Patent CA-2179583-A1 (CA)
Inventor: HOLDER DONALD
IPC: G05D16/10
Filed: 1996-06-20
Abstract: A flow responsive pressure regulating unloader suitable for use between a positive displacement fluid pump and a fluid consuming device connected to the pump. The unloader includes a housing having an inlet port connected to an outlet port, and a by-pass port. A fluid pressure regulating valve is connected between the inlet port and the by-pass port to limit the maximum fluid pressure at the inlet port. A flow responsive valve also is connected between the inlet port and the by-pass port. Fluid flow from the inlet port to the outlet port creates a pressure drop across an orifice. The pressure differential is applied across a piston to close the flow responsive valve. When flow from the outlet ceases, the pressures across the piston become equal and the fluid pressure on the flow responsive valve opens the valve to divert fluid to the by-pass port.

Inventor: HONDA YASUAKI
IPC: G06T19/00
Filed: 1996-07-10
Abstract: Volume of communication necessary for displaying moving images is minimized. When an object is moved on a client terminal 13-1, a message indicating the movement of the object is transmitted to a server terminal 11-1. The server terminal 11-1 transmits the message to client terminals 13-2 and 13-3. Each of the client terminals 13-1 through 13-3 stores a message table in advance to execute the message. According the message table, an image for locally moving an object 101 is generated and displayed.          This novel setup transmits information about the update of an update objects composed of a plurality of sub objects each of which state is subject to change, in a minimum transmission volume. This, in turn, allows cooperative operations of the plurality of sub objects to be smoothly displayed in a three-dimensional virtual reality space shared by a plurality of users.

Patent CA-2185976-A1 (CA)
Title: Tamper evident, child-resistant closure
Inventor: TROUT STANLEY D
IPC: B29C45/44
Filed: 1996-09-19
Abstract: A child-resistant, tamper-evident closure for sealing an open-topped container having an external thread formed on a neck finish includes a combination of inner and outer caps where the inner cap includes a tamper-evident band which is connected to the remainder of the inner cap by a series of frangible elements.  The inner cap further includes a series of folded ratchet-like tabs which are in a locked position behind an annular bead.  The tabs are arranged so as to engage an annular lip on the neck finish.  The outer cap snaps over the inner cap and includes a series of ratchet teeth which are directed toward the inner cap.  The top surface of the inner cap includes a series of depressions which are sized and arranged for engagement with the series of ratchet teeth.  The child-resistant arrangement permits the outer cap to turn relative to the inner cap in a counterclockwise direction.  In the clockwise direction, the ratchet teeth and depressions are in engagement such that turning of the outer cap will advance the inner cap into threaded engagement.  Removal of the inner cap from the neck finish is achieved by ovalizing the outer cap so as to bring into engagement ribs on the inner cap with ribs on the inside surface of the sidewall of the outer cap.  By means of rib engagement and frictional interference, the outer cap is used to remove the inner cap.
