Patent CA-2129854-A1 (CA)
Inventor: HARFORD JACK R
IPC: H04N5/44
Filed: 1993-10-30
Abstract: Dans un récepteur de télévision, une première chaîne d'amplificateurs FI comprend un premier amplificateur à régulation de gain monté en cascade avec un deuxième amplificateur à régulation de gain, et une seconde chaîne d'amplificateurs FI comprend un troisième applificateur à régulation de gain monté en cascade avec un quatrième amplificateur à régulation de gain. Les deuxième et quatrième amplificateurs à régulation de gain sont régulés de manière analogue par un signal de régulation automatique de gain (AGC), et les premier et troisième amplificateurs sont régulés de manière analogue par ce signal AGC retardé d'un intervalle équivalent. Un amplificateur RF est sensible, par rapport à la régulation de gain, à ce signal AGC lorsqu'il présente un retard encore plus important, et un changeur abaisseur de fréquence fournit une première réponse de détecteur à un signal RF amplifié, cette réponse étant appliquée aux première et seconde chaînes d'amplificateurs FI par des filtres respectifs à sélection de fréquence. La réponse du premier amplificateur FI est transposée par abaissement de fréquence afin de générer un son FI. La réponse du second amplificateur FI est détectée afin de récupérer le signal vidéo. Un détecteur AGC détecte les crêtes des impulsions de synchronisation dans le signal vidéo afin de développer le signal AGC.

IPC: H04B1/40
Filed: 1994-09-23
Abstract: This  invention  provides  a  method,  and  apparatus  for performing the method, for reducing the power consumption of a radiotelephone. The method includes the steps of (a) receiving with a receiver of a radiotelephone at least a Word  Synchronization  pattern  from  a  frame  that  is transmitted over a control channel; (b) receiving a first repeat  of  a  control  message that  follows  the  Word Synchronization  pattern  within  the  frame;  and  (c) determining if the first repeat was correctly received. If the  first  repeat was  correctly  received,  the  method includes a further step of (d) determining if at least one reception-related criteria is met. If the reception-related criteria is determined to be met, the method includes a further step of (e) selectively removing operating power from one or more portions of the radiotelephone receiver for a predetermined time period during a remainder of the frame. The at least one reception-related criteria is a Message  Error Rate  (MER)  that  indicates  a  number  of correctly received frames out of a total number of n last received frames. The reception-related criteria may also include a difference between a minimum Received Signal Strength Indicator (RSSI) value and a maximum RSSI value that are detected during a predetermined interval of time.

Title: Method of and apparatus for activating fish attractors having a luminescent surface which is light activatable
Inventor: DOLPH JAMES L
IPC: F21V33/00
Filed: 1994-11-16
Abstract: A method of and device for activating a luminescent fish attractor which is light activatable with a flash element connected with a battery housed in a battery casing via a voltage building circuit to provide highly intensive light flashes.  The casing is provided with a tubular enclosure having a first end receiving light flashes from a flash element, and a second remote open end.          The enclosure has an interiorly facing, substantially opaque, light reflective surface for concentrating light rays emitted from the flash element.  The lure or attractor is first placed in the enclosure by inserting it through the remote open end.  The flash element is then repetitively powered, and the flashed light rays emitted are directed successively into the enclosure.  The light rays are repetitively bounced from one reflective surface portion to another along the light reflective surface to impinge upon all luminescent surfaces of the attractor to thereby cause them to later emit light in low light conditions for a protracted period of time, after which the lure or attractor is removed from the enclosure.
