Patent CA-2037881-A1 (CA)
Inventor: LOVELL JOHN G SR
IPC: A63F3/06
Filed: 1991-03-08
Abstract: An electronic alpha-numeric digit displaying device, together with a control unit and electronic circuitry appropriate to the encoding, sending, receiving, decoding, and displaying of data as used in various games, such as Bingo, Keno, or the like, in which a plurality of players may participate.  In the exemplary game of Bingo, for instance, light-weight plastic balls, each marked with a letter and a number, are randomly selected and deposited into apertures in a console, by which action they are automatically identified through the breaking of one row and one column infra-red light beam of a coordinate grid of such beams.  Through electronic encoding, transmitting/receiving, and decoding, the aforesaid letter-number combination is substantially instantaneously displayed in two places on a display board.  One of these locations is on letter-labeled rows by the sequential order of the selected letter-number; the other location is on a separate row where appearance is determined entirely by the sequence in which the letter-number combination is selected. The numbers are continuously selected and progressively displayed until a round of play has been completed in accordance with various rules of the game being played. When this occurs, the display board is cleared and all of the balls are reloaded to begin the next round of play.  The console contains manually operated controls which affect the game data stored in memory and thus the display board, also.

Abstract: A window operator and lock structure for control-ling a window sash supported by a hinge for pivotal motion relative to a window frame, including a base mounted to the frame and supporting a drivable sun gear, and a planet gear engaging the sun gear and supported on the base for pivot-ing about the sun gear axis.  One linkage is secured to the planet gear axis and the window sash to control motion of the sash.   A locking structure secures the sash to the frame, which structure is operated by a gear arm fixedly secured to the planet gear and a cam link between the gear arm and the locking structure.  Selective operation of the locking structure is effectuated by biasing the cam link against a fixed pin which engages a slot in the cam link to secure the cam link against operating the locking struc-ture, and a trip on the sash which engages the cam link when the sash is closed against the frame to disengage the cam link from the pin.

Title: Method of preparing heteroalicyclic n-nitro compounds
Inventor: MILLAR ROSS WOOD
IPC: C07D263/26
Filed: 1992-01-22
Abstract: A method of preparing heteroalicyclic N-vitro compounds consists of the steps of reacting a heteroalicyclic N-monosilylated compound with dinitrogen pentoxide, preferably within an inert organic solvent and within the temperature range -10°C to +10°C, and separating the N-vitro product from the silyl nitrate co-product thus obtained.      The present nitrodesilylation method is capable of producing heteroalicyclic N-vitro compounds in high yields of typically 60-80%, and generates a silyl nitrate co-product which is relatively easy to remove by distillation in the presence of excess N2O5. Reagents containing two or more N-silyl groups per molecule can be employed yielding useful high explosive materials containing a corresponding number of N-vitro groups per molecule.

Filed: 1992-07-30
Abstract: Fast resoure assignments, especially needed in microcellular network architectures having many fast moving subscribers and high traffic volume, is provided through the use of a priority based resource assignment apparatus and procedure.  Part of the communication resources in a cellular network, for example, one carrier frequency and/or one time slot, or particular code division multipleaccess sequences are dedicated to the execution of the assignment procedure. Available communications resources are auctioned to cellular subscribers contending for resoures based upon a level of priority assignment to each contending subscriber. The priority level may be based on such things as the quality of service to which a customer subscribes or the particular needs of a subscriber at the time the subscriber is contending for resources, for example,the subscriber's request for resources may be prompted by a need to make a handoff.  The procedure involves an auction period when a determination is made regarding which of a group of contending subscribers has the highest priority level.  The procedure then enters a resource assignmentperiod where an available communications resource is actually assignment to the subscriber having the highest priority level.  The auction and assignment periods are then repeated for the remaining contending subscribers until there are no longer any contending subscribers or there are no longer any available resources.  Fast resource assignment could be used to increase system capacity and efficiency of spectrum utilization through the ability to perform speech activity resource sharing.

Filed: 1992-09-08
Abstract: A speech coding apparatus and method for use in a speech recognition apparatus and method.  The value of at least one feature of an utterance is measured during each of a series of successive time intervals to produce a series of feature vector signals representing the feature values.   A plurality of prototype vector signals,  each having  at  least  one  parameter  value  and  a  unique identification value are stored.   The closeness of the feature vector signal is compared to the parameter values of the prototype vector signals to obtain prototype match scores for the feature value signal and each prototype vector signal. The identification value of the prototype vector signal having the best prototype match score is output as a coded representation signal of the feature vector   signal.    Speaker-dependent   prototype   vector signals  are  generated  from  both  synthesized  training vector signals and measured training vector signals.  The synthesized  training  vector  signals  are  transformed reference feature vector signals representing the values of features of one or more utterances of one or more speakers in a reference set of speakers.   The measured training feature vector signals represent the values of features of one or more utterances of a new speaker/user not in the reference set.
