Publication number: 20080084498Abstract: Disclosed are methods and devices for the irises of cameras. A non-mechanical or electro-optical camera iris includes a controlled material that is configured to change from substantially transparent to substantially opaque by changing the state of the controlled material to effectively adjust the size of the central window of the iris. Accordingly, the described electro-optical iris would add little or no additional bulk to a small mobile communication device camera. The controlled material can be electrically controlled or thermally controlled. The controlled material can be a set of separately controllable areas substantially surrounding the central window. The set can have an ordering from outer to inner so that outer separately controllable areas in the set substantially surround inner separately controllable areas in the set. Accordingly, by changing the opacity of the outer area from transparent to opaque, the size of the central window of the adjustable aperture is reduced.Type: ApplicationFiled: October 4, 2006Publication date: April 10, 2008Applicant: MOTOROLA, INC.Inventors: FAN HE, MICHAEL W.

Patent number: 6021332Abstract: A radiotelephone (100) includes a main battery (101) and is operable on a first communication system. A supplemental module (102) may be attached to the radiotelephone. The supplemental module may include a second RF communication circuit for communicating with a second communication system. This allows the user to configure the radiotelephone for communication with currently available systems. The supplemental module may further include an auxiliary battery for providing extended battery operation. The radiotelephone includes a discharging and charging circuit (310) to control the discharge and charge of the auxiliary and main batteries in a way that allows uninterrupted, continuous operation of the radiotelephone.Type: GrantFiled: April 1, 1997Date of Patent: February 1, 2000Assignee: Motorola, Inc.Inventors: William P.

Patent number: 5737685Abstract: A satellite communication system (SCS)(100) and method (300) are provided that provide a geographically co-located user assignment system. For unit-to-unit communication, each group of subscriber units is instructed to operate in a half-duplex unit to unit mode. The geographically co-located user assignment system comprises an assignment unit (201), a storage unit (203), and an instruction unit (205) such that a first subscriber unit (204) initiates unit to unit communication with at least a second subscriber unit (206, . . . ) in the first subscriber unit's user group utilizing a multiple access channel assigned to that group by transmitting on an assigned satellite downlink frequency of the multiple-access channel on a push-to-talk basis.Type: GrantFiled: December 20, 1995Date of Patent: April 7, 1998Assignee: Motorola, Inc.Inventors: Robert J.

Patent number: 5426825Abstract: A flexibly adjustable mounting clip assembly and method for providing the assembly for a pager includes a swivel assembly (104) for raising and rotating the mounting clip (102) approximately 180.degree. to provide a reversibly positioned clip. The clip allows for positioning in an introverted position, i.e., facing the bent section toward the pager and for positioning in an extroverted position, i.e., facing away from the pager. In addition, a transparent portion may be positioned below the clip assembly for allowing observation of the information display of the pager.Type: GrantFiled: January 29, 1993Date of Patent: June 27, 1995Assignee: Motorola, Inc.Inventors: Leonid Soren, Shrirang Jambhekar, Albert L.

Patent number: 5396643Abstract: The present invention includes a low-earth satellite-based paging broadcast system (100) and method (200, 300) that maximizes spectral efficiency and minimizes power expenditure for the broadcast of paging messages by broadcasting the messages to terminator- or originator-selectable portions of the total system coverage area. The terminator selects a long-term preferred geographic area (LTPGA), and optionally, a short-term preferred geographic area (STPGA). The originator provides the terminator ID, the message, and optionally provides a customized preferred geographic area (CPGA). Terminators and originators can easily modify the selectable geographic areas (SGA(s)): LTPGA(s), STPGA(s), and CPGA(s). The gateway converts the SGA(s) to addressable coverage areas (ACA(s)), and transmits a signal including the paging information, and ACA(s) to at least a first communication satellite (COM SAT).Type: GrantFiled: August 24, 1992Date of Patent: March 7, 1995Assignee: Motorola, Inc.Inventors: Michael W.

Patent number: 4754467Abstract: An improved digital signal detector for indicating the presence of digital data used in a communication system. While attempting to detect valid data, the detector buffers an incoming signal in a first-in, first-out buffer and allows locally generated data, instead of the buffered signal, to be coupled to an output. After detecting valid data, the detector estimates where in the buffer valid data commenced and either releases data from that point or further delays the signal up to the maximum length of the buffer before releasing it to the output. The invention provides high sensitivity and rapid detection, reduces variation in detection time over previous methods, and allows locally generated data to be inserted into the signal path without loss of valid data.Type: GrantFiled: July 1, 1987Date of Patent: June 28, 1988Assignee: Motorola, Inc.Inventors: Dean E. Banwart, Michael W. Frenzer, Thomas J. McClaughry
