Filed: 1999-01-11
Abstract: Contrast to the pre-art, this prawn trap presents itself as an opaque object with dark openings on the sea door, providing an ideal hiding and feeding spot for the usually timid prawns. When the two large deep mash cone entrances have released a concentrated scent from the inner bait jar into the current, it is irresistible for prawns to follow the scent and swim into the trap. The feeding activities of the prawns in the trap will release more scent and further enhance the attraction for other prawns to join in the feeding. When the trap is retrieved, the minimum water resistant is encountered as the trap is in its aerodynamic position.

Patent CA-2264746-A1 (CA)
Inventor: HAARTSEN JACOBUS CORNELIS
IPC: H04B7/26
Filed: 1997-08-22
Abstract: Radio beacon transmission between a private radio communications base station and a mobile terminal within the transmission range of the private radio communications base station designed to prevent interference with overlapping uncoordinated private radio communications networks is provided by jittered beacon transmission. The private base station transmits radio beacon bursts at jittered time intervals, which vary pseudo-randomly to prevent repeated radio beacon collisions between uncoordinated private radio communications networks with overlapping transmission ranges. The beacon time jittering is performed pseudo-randomly in a pattern which is associated with a base station identification value. The mobile terminal derives the base station associated identification value and status information from a received radio beacon and determines if the base station is available for communications with the mobile terminal. The mobile terminal further synchronizes with the jittered base station beacon transmissions based on the pre-determined jitter generation function associated with the base station identification value derived from the received radio beacon. The mobile terminal is thereby able to readily maintain synchronization with one or more private radio communications network base stations without losing synchronization due to repeated radio beacon burst collisions between the base stations.

Filed: 1999-05-28
Abstract: In a single-carrier or multi-carrier modulator (MOD), data symbols are modulated on at least one carrier in accordance with at least one constellation scheme. Idle data symbols are replaced by null data symbols and the latter null data symbols are associated with a low power constellation point of the at least one constellation scheme. The constellation points associated with the data symbols are randomly transformed into constellation points of equal power. In this way, idle data symbols are transferred with minimised power and sufficiently randomised to allow equaliser training and/or tracking at the receiving demodulator (DMOD) and to avoid high crest factors in multi-carrier systems.
Patent CA-2272938-A1 (CA)
Inventor: REINICKE ROBERT H
IPC: F16K31/06
Filed: 1996-12-30
Abstract: A valve construction relies upon solenoid-driven axial elongation of an annular magnetostrictive core element (30) for opening displacement of an elongate poppet valve member (35) that is carried within the annulus of the core element. A first stiffly compliant preload (38) independently urges the poppet valve member into its seated position of lock-up at valve closure, and a second stiffly compliant preload (31) independently prestresses the annular magnetostrictive core element into a fixed reference abutment within the valve housing. The preferred material of the core is Terfenor-D, which offers a strong elongation response to inductively coupled excitation. The elongation response closes a pretravel clearance prior to flange engagement with the poppet valve member and displaces the poppet valve member out of its normal valve closing engagement with the valve seat.

Patent CA-2283921-A1 (CA)
Inventor: KLAS ERNST
IPC: D21H23/78
Filed: 1997-12-09
Abstract: In conventional methods absorbent base paper is impregnated by being passed through an aqueous solution of the impregnating agent and then conveyed to a drier after the excess has been squeezed off by means of metering rolls. The quantity of resin applied and the residual moisture are checked at set intervals using sample pieces cut out from the web and in the case of deviations the setting of the metering roll or the throughput speed are corrected. The inventive method uses an automatic regulating device. The basis weight of the freshly impregnated, wet web is measured and adjusted to a predetermined control input. The residual moisture of the dried web is measured and adjusted to a set value, for example by influencing the speed of the drying air which is circulated during the last drying phase. The quantity of resin applied is calculated from the basis weight and the residual moisture of the dried web and the basis weight of the untreated web. This is then compared to a set value to give the control input for metering. The method is especially suitable for producing cosmetic films for refining surface of chip board for the furniture industry.

Abstract: The present invention discloses a harmonic rejection load pull tuner. The tuner of the invention has a large-band tuner having an input and an output, and a transmission line having a longitudinal axis. The transmission line has an input connected to the output of a DUT and an output connected to the input of the large-band tuner. In parallel with the transmission line is at least one stub, the at least one stub having a length adapted to reflect out an nth order harmonic of a base frequency, where n is an integer greater than 1. The tuner of the present invention can be used to perform input or output characterisation (or both) of a DUT, by selectively reflecting out at least one harmonic frequency of the base frequency. Consequently, the characterisation of the DUT is improved, since the effects of the harmonics are considerably reduced. The present invention also concerns a method for performing input or output characterisation.
