Patent number: 5548803Abstract: A booster usable in a radio telephone communication system can amplify and repeat both analog and digital representations of communications. The unit monitors control channel communications going to subscriber units and reverse control channel responses from subscriber units. When a digital traffic channel assignment is detected, the booster directs the subscriber unit to a different traffic channel pair. The booster communicates with the subscriber unit on the traffic channel pair assigned by it to the subscriber unit. The booster communicates with the cell site on the channel pair assigned by the cell site. Digitized communications from the subscriber unit are amplified only during the associated time intervals. Hence, other communications in different time intervals on the same message channel are not effected. Analog conversations and other message channels can be simultaneously boosted and retransmitted.Type: GrantFiled: March 31, 1992Date of Patent: August 20, 1996Assignee: Orion Industries, Inc.Inventor: Michael W. Evans

Patent number: 5546293Abstract: A multiple element reflector usable with an elongated light source in a strobe unit provides wide fields of view in both horizontal and vertical directions when the unit is mounted on a wall. The reflector includes a first, elongated, curved reflector element which extends generally parallel to the elongated light source. At least second and third centrally located reflector elements extend between the first reflector element and the light source. The first reflector element provides illumination generally in horizontal and vertical directions perpendicular to the elongated source. The second and third centrally located reflector elements provide illumination in a direction generally along the elongated source.Type: GrantFiled: June 1, 1995Date of Patent: August 13, 1996Assignee: Pittway CorporationInventor: Walter J. Moran, III

Patent number: 5537785Abstract: A building fascia is disclosed, which comprises an elongate gutter and a soffit. Being made from sheet aluminum, steel, or copper, the gutter has back, bottom, and front walls and a channel extending along and into the gutter from the back or bottom wall, preferably from the back wall. Being made therefrom or from vinyl or other polymeric material, the soffit has an edge portion inserted into the channel. Lips formed on the edge portion and on one of two side walls of the channel have sufficient flexibility and are shaped to permit the edge portion to be readily inserted with a snap action but to restrain the edge portion against being withdrawn from the panel. Preferably, one of the side walls of the channel is spaced narrowly from the bottom wall of the gutter, the narrowly spaced walls flaring into the gutter so that ice forming between the narrowly spaced walls is extruded into the gutter.Type: GrantFiled: September 12, 1994Date of Patent: July 23, 1996Assignee: ZMC, Inc.Inventor: Richard J.
