Patent CA-2116494-A1 (CA)
Inventor: PAULEY IAN B
IPC: F28D20/00
Filed: 1994-02-25
Abstract: A water storage tank is composed of a plurality of interlocking or interconnectable segments which when assembled together form at least a base and side walls of the tank, and a thin plastics liner to line the interior of the tank. The interlocking or interconnectable segments may be formed by moulding from a rigid thermally insulative foam material such as polystyrene. The segments may be held in position by bands or straps around the tank. The tank may be a hot water tank with an electric heating element suspended into the tank from the lid of the tank and a water inlet and water outlet also entering through the lid. The tank may be arranged so that it is refilled with cold water and reheated only at night on low tariff electricity.

Title: Digital telephone, cable tv system and local exchange bypass network
Inventor: BARAN PAUL
IPC: H04H20/76
Filed: 1992-09-16
Abstract: Cordless telephones (38) generate call relay packets. Packets from each cordless telephone are polled by an upstream polling unit avoiding multi-unit interference. Cell packets are transmitted via a cable TV system (36). Radiated frequencies of the cordless telephones are shifted in frequency as they enter or leave the TV  feeder cable to allow frequency reuse. The upstream polling unit appends header information on the cell packets and converts them into standard SONET ATM protocol packets. The cell relay packets are switched by a cell relay type switch to create a cost-effective, alternative telephone system.
Patent CA-2121366-A1 (CA)
Inventor: ROES JOHN B
IPC: H05F1/02
Filed: 1992-10-19
Abstract: A permeable electrostatic shielding method and apparatus is disclosed that is suitable for use in shielding portable electronic devices such as calculators, smart cards and radios. Such electronic devices require protection from the electrostatic discharge occurring when a user accumulates an electrostatic charge and contacts a conducting surface of the electronic device. The resulting electrostatic discharge creates capacitively-coupled voltage transients in the digital circuits within the electronic device. The present invention prevents local charge accumulation on the surfaces of such electronic devices, which transmit and receive electromagnetic radio waves, without blocking the electromagnetic radiation essential to device function. One embodiment of this permeable electrostatic shield is formed by depositing a conductive layer of controlled thickness comprising a plurality of closely-spaced conductors that are electrically connected at one end to form a practical electrostatic shield permeable to RF electromagnetic radiation above 15 MHz.

Title: Method of managing a speech memory, and apparatus therefor
Inventor: ACKERMANN UWE
IPC: G06F12/02
Filed: 1994-09-23
Abstract: Abstract A method of managing a speech memory (VMEM) and an assembly therefor are disclosed.      To enable a plurality of users (U1, U2, U3, U4) to access the speech memory, the latter is divided into user memory areas (S1, S2, S3, S4) and a common memory area (SALL). By adding a portion (S4') of the common memory area to one of the user memory areas (S4') or vice versa, the size of this user memory area is adapted to the memory space requirements (Min4) of the user (U4).            The capacity of the speech memory (VMEM) is effectively utilized, since, as far as possible, no free memory space is assigned to the users (U1 to U4) which will not be used by them. The assembly can be used, for example, as a voice mailbox in a telecommunications system.            (Fig. 2b)

Title: Diagnostic method and apparatus for a cable television interediction system
Inventor: PARIKH HIMANSHU
IPC: H04N7/173
Filed: 1993-06-10
Abstract: A diagnostic method and apparatus for a cable television interdiction system is provided. One or more diagnostic modes each corresponding to a particular problem or state associated with the interdiction unity may be entered into by the interdiction unit. The cycle of disabling the television signal provided to the receiving apparatus and pulsing either or both the television signal provided to the receiving apparatus and/or the LED is repeated until a transaction is received from the headend cancelling the diagnostic mode. Thus, the pulsing of the television signal provided to the receiving apparatus alerts the user of the receiving apparatus that a problem has occurred to the interdiction unit, and this information may be provided by the user to the cable television operator. Likewise, the pulsing LED coupled to the interdiction unit may alert a technician working on the interdiction unit as to the cause of the problem. In a preferred embodiment, the LED may be located on a tamper override module (TOM) (400) inserted into the interdiction unit by a technician in order to service the interdiction unit.

IPC: G06F17/50
Filed: 1995-04-21
Abstract: On-the-Fly Model Checking with Partial-order State Space Reduction ABSTRACT An on-the-fly verification system which employs statically-available information to reduce the size of the state space required to verify liveness and safety properties of a target system consisting of asynchronous communicating processes.  The verification system generates a verifier from a description of the target system and a specification of the property to be verified.  The verifier models the target system as a set of finite state machines, constructs a state space containing a graph of nodes representing states of the target system and transitions between the states, and uses the state space to verify the property.  The size of the state space is reduced by using information from the description and the specification to divide transitions from a node into per-process bundles and to determine which bundles of transitions must be included in the state space and which may be left out of the state space.  The state space reduction technique never increases the size of the state space and often reduces it by orders of magnitude.
