Title: Improved communications marketing system
Inventor: GREGOREK MARK R
IPC: H04M3/487
Filed: 1995-07-19
Granted: 2007-01-23
Abstract: A communications marketing system (10) for selectively modifying an existing communications network by modifying a portion of the processing software permits transmitting a generally continuous pre-recorded announcement to a network station (12) which has been temporarily disconnected from a called network station (20) and placed on hold. The network allows an identified called station connected to a first call from a first party at a first network address to receive a second call from a second party at a second network address. The network interrupts the called station and signals the called station of the second call. The called station can then choose to connect to the second call and temporarily disconnect the first party, placing the first patty on hold and thereafter the called station may switch between the first and second calls. The system plays at least one announcement to the party placed on hold by the called station until the called station signals to reconnect to the party on hold, at which time the playing of the announcement is terminated. The system further provides a custom audio and/or visual message and/or menu in lieu of a dial tone signal to a party initiating a connection with the network.
Patent CA-2198538-C (CA)
Inventor: EHNOT DONALD JAMES
IPC: F25D3/11
Filed: 1997-02-26
Granted: 2000-05-16
Abstract: The present invention is an immersion freezer which employs a postcooling chamber. The immersion section of the freezer initially immerses all or part of the items to be frozen (typically food items) in a bath of a liquid refrigerant to impart a crust freeze on the items, which locks in moisture and prevents clumping. The postcooling chamber, located underneath the immersion section, then uses the vaporized refrigerant from the immersion section to complete the freezing process while also maximizing efficiency. The postcooling chamber also imparts agitation to the items (which further prevents clumping) through the use of a series of cascading conveyor belts.

Granted: 2001-11-20
Abstract: The invention provides a transmission power control apparatus for a mobile radio satellite communication system which  allows   frame   synchronization  maintenance   and synchronization acquisition of a receiving station and optimum transmission power control with a simple construction which does not effect complicated control.  The transmission power control apparatus includes a transmission power control loop provided in each of a gateway station and a terminal/mobile station for controlling a transmission power of the station. The transmission level during transmission is monitored and compared with a preset transmission level to change over an average time for sampling of the error between the transmission levels to vary the response speed of the transmission power control loop.  When the channel for current use is to be changed over from a signalling channel to a communication channel, the transmission power is controlled so that there is no trouble for continuous synchronization of the reception side.  But, when the channel is to be changed over from the communication channel to the signalling channel, the transmission power is controlled rapidly to a standard level so that there is no trouble in synchronization acquisition or data transmission.

Abstract: A generator for an internal combustion engine which employs an induction motor as an alternator and enables generation of specified power regardless of the number of rotations of the internal combustion engine. The generated energy P  of an alternator (1) is limited to a value not more than an upper limit value Pmax (Figure 5) and not less than a lower limit value Pmin (Figure 6) or to a target value Pc (Figure 7), regardless of the mechanical rotational speed N1 of a rotor 1R. Such control of the generated energy is realized by controlling the speed N2 of a rotating magnetic field electrically generated on a three-phase winding of the rotor 1R in response to the mechanical rotational speed N1 of the rotor 1R, so that the relative speed N of the rotating magnetic field generated by the rotor with respect to a stator coil is maintained at a speed not higher than an upper limit speed Nmax and not lower than a lower limit speed Nmin or at a target relative speed Nc.

Abstract: A method and apparatus for detecting an aberrant velocity of a motor used to drive an element in a plastics processing machine, such as an injection molding machine, for example. The velocity of the motor is detected by a first sensor and a machine parameter associated with the machine operation is provided. A velocity limit is determined based upon the machine parameter and an error signal is generated when the motor velocity exceeds the velocity limit by more than a predetermined tolerance value. Preferably, the machine parameter comprises the position of the element driven by the motor, which is sensed by a sensor, such as a linear displacement transducer. The velocity limit can be based upon this measured element position as well as data entered for the particular machine, such as a minimum element position, a maximum element position, and a maximum motor velocity, such that a desired motor operating envelope is defined. Also, the motor velocity command is preferably set equal to the velocity limit when it exceeds the limit. In another embodiment, the machine parameter comprises a motor velocity command for controlling the velocity of the motor. The velocity command is compared to the previous velocity command and the velocity limit is set equal to the velocity command when it exceeds the previous command.

Title: Resource allocation mechanism in packet radio network
Inventor: MUSTAJARVI JARI
IPC: H04W8/26
Filed: 1998-03-25
Granted: 2008-06-10
Abstract: In a packet radio system (e.g. a GPRS), a network (BSS) has two different alternatives for allocating a radio resource to a mobile sta-tion (MS). In a first allocation alternative the ra-dio resource is allocated using an uplink counter block identifier (USF) transmitted with down-link blocks. In a second allocation alterna-tive the radio resource is allocated in a sepa-rate signalling message. A corresponding down-link block then also has an uplink counter block identifier (USF) which can acquire only a lim-ited number of possible values. If all identifiers (USF) are allocated to different mobile stations, allocation alternative 2 cannot be used. In the invention the network leaves at least one identi-fier (USF) unallocated to any mobile station. In addition, the network either (1) uses the identi-fier in downlink blocks corresponding to blocks reserved using the second allocation alternative;  or (2) at least one uplink counter block identifier (USF) is separately determined, said identifier denoting a reserved uplink block which the mo-bile station cannot use for transmission without a separate authorisation.

Abstract: A dictionary based data compression and decompression system where, in the compressor (10), when a partial string W and a character C are matched in the dictionary (13), a new string is entered into the dictionary with C as an extension character on the string PW where P is the string corresponding to the last output compressed code signal. An update string is entered (113) into the compression dictionary for each input character that is read and matched.  The updating is immediate and interleaved with the character-by-character matching of the current string. The update process continues until the longest match is found in the dictionary. The code of the longest matched string is output (106) in a string matching cycle. If a single character or multi-character string "A" exists in the dictionary, the string AAA...A is encoded in two compressed code signals regardless of the string length. This encoding results in an unrecognized code signal at the decompressor. The decompressor (40), in response to an unrecognized code signal, enters (Fig. 8) update strings into the decompressor dictionary (43) in accordance with the recovered string (161) corresponding to the previously received code signal, the unrecognized code signal, the extant code of the decompressor and the number (135) of characters in the previously recovered string.
