Title: Conditional access information arrangement
Inventor: TAMER GREGORY GEORGE
IPC: H04N7/16
Filed: 1995-03-15
Abstract: Apparatus in a receiver, for processing transmitted entitlement control information, includes a packet transport processor (13-15, 19) for selecting signal packets having payloads containing a conditional access payload header and a remaining payload of entitlement data.  Respective payload headers include groups of bytes which are coded in a manner to allow or disallow the respective receiver from processing the entitlement data.  A conditional access filter (30) preprogrammed with a subscriber specific conditional access codeword examines respective byte groupings of the conditional access header for a match with the subscriber specific conditional access codeword. Only if a match occurs is the processor peemitted to process (17, 18, 21-24) the entitlement data.  The entitlement data is thereafter utilized to generate (31) decryption keys for descrambling (16) portions of the transmitted signal.

Title: Synchronised timing device
Inventor: BIRRELL PETER
IPC: H05B37/02
Filed: 1996-10-28
Abstract: A timing device which is associated with a light level sensor and which is arranged to provide a time-out signal to a relay after a predetermined time has elapsed following detection of a low light condition and initial energisation of the relay. The device provides for synchronisation of an initiation time T1 and, hence, a time-out signal generating time T2 with respect to a periodically occurring event time T3 (for example, sunset time) in order that the desired time of generating the time-out signal might be re-established following interruption of power to the device. Should loss of power occur, the last entered event time T3 is employed to synchronise the initiation time T1 and, hence, the signal generating time T2, when detection of a predetermined light level next occurs following re-establishment of power to the device.

Title: Goalie training apparatus and method of using a goalie training apparatus
Inventor: ORMONDROYD THOMAS
IPC: A63B69/00
Filed: 1996-11-06
Abstract: A goalie training apparatus has a first plurality of semi-circular wedge-shaped barriers attached to an upper glide surface of a slide board along an arc and at least one other barrier attached to the upper glide surface separatedfrom the first plurality of barriers leaving a portion of the glide surface unobstructed. The arcuate faces of the barriers present multi-angular push-off points important for goalie training, as goalies must move in various directionswithin the goal crease. The barriers are preferably attached to the glide surface with high strength hook and loop fasteners, possibly in combination with bolts, screws or rivets. Wearing a foot covering with a low coefficient of friction in relation to the glide surface, a goalie stands atop the unobstructed glide surface and pushes a foot against one barrier and glides or shuffles along the glide surface to another barrier/push point. The second barrier may be a plurality of barriersand represents the goal or goal posts. The first plurality of barriers representtarget points in front of a goal that are important for goalies practicing "going out" and "cutting down" angles.

Patent CA-2202660-A1 (CA)
Title: All-optical processing in communications systems
Inventor: ELLIS ANDREW DAVID
IPC: H04B10/2507
Filed: 1995-10-19
Abstract: An all-optical processing system is described for converting or interfacing optical signals from a wavelength division multiplexed (WDM) form to an optical time division multiplexed (OTDM) form, where the initial WDM signal typically comprises a non-return to zero (NRZ) signalling format. The system comprises a plurality of NRZ data modulated, cw optical WDM channels (w, x, y, z), which are cross-phase modulated, and thus are spectrally broadened, in an optical non-linear element (745), by a strong clock pulse signal. The resultant signal comprises an RZ representation of the original NRZ signal.  The RZ signal is temporally shifted by a dispersive element (760), which temporally shifts each wavelength channel by a predetermined amount, to produce a wavelength-interleaved OTDM signal. The signal is then wavelength converted by cross-phase modulation with a cw control beam in a second non-linear optical element (770), to provide a single wavelength OTDM signal.
