Patent number: 10242017Abstract: Methods and apparatus for modifying the feature set of data collection devices are disclosed. Requests are receiving at a computer system different from the data collection device for a new configuration of the data collection device, the request including an identifier for the data collection device, identification of one or more features, and for each identified feature, an indication to modify the operation of a feature. The identifier may comprise an identifier that is unique for a particular data collection device or an indication of a group of devices, e.g. a model number. Prior to authorizing the new configuration, a determination may be made as to whether the identified data collection device(s) are suitable for the new configuration by consulting a configuration database. To implement the new configuration, an encoded authorization file is generated based on the requested configuration and the identifier of the data collection device(s).Type: GrantFiled: January 17, 2014Date of Patent: March 26, 2019Assignee: HAND HELD PRODUCTS, INC.Inventors: Guy H.

Publication number: 20080228773Abstract: A client apparatus to receive scan data. The client apparatus comprises configuration files including a plurality of settings to control operations of the client apparatus, logic to receive scan data and to request web pages from a web server using the scan data and the settings in the configuration files. The configuration files separate the functionality of the client apparatus from the content of the web pages so that neither the configuration files nor the web pages depend on the particular platform or hardware setup of the client apparatus.Type: ApplicationFiled: March 14, 2007Publication date: September 18, 2008Applicant: HAND HELD PRODUCTS, INC.Inventors: James W.

Publication number: 20070237466Abstract: A system for retaining an optical subassembly in a shell of a communications module is disclosed. The system reduces stress imposed on a hermetic package of the optical subassembly during lead interconnection procedures while ensuring thermal contact of the package with a thermal pad mounted in the shell. In one embodiment, the system includes a spring clip comprising a head portion that defines a seating surface, as well as first and second arms. The seating surface is shaped to engage an outer surface of a nosepiece of the optical subassembly. The first and second arms extend from the head portion so as to define a āUā-shaped configuration with the head portion. The head portion is shaped so as to provide a resilient force against a flange of the nosepiece when the flange and spring clip are received in a groove defined in the shell during assembly.Type: ApplicationFiled: April 5, 2007Publication date: October 11, 2007Applicant: Finisar CorporationInventors: Chris Togami, James W.

Patent number: 6679621Abstract: A lens comprises a bottom surface, a reflecting surface, a first refracting surface obliquely angled with respect to a central axis of the lens, and a second refracting surface extending as a smooth curve from the bottom surface to the first refracting surface. Light entering the lens through the bottom surface and directly incident on the reflecting surface is reflected from the reflecting surface to the first refracting surface and refracted by the first refracting surface to exit the lens in a direction substantially perpendicular to the central axis of the lens. Light entering the lens through the bottom surface and directly incident on the second refracting surface is refracted by the second refracting surface to exit the lens in a direction substantially perpendicular to the central axis of the lens. The lens may be advantageously employed with LEDs, for example, to provide side-emitting light-emitting devices. A lens cap attachable to a lens is also provided.Type: GrantFiled: June 24, 2002Date of Patent: January 20, 2004Assignee: Lumileds Lighting U.S., LLCInventors: Robert S. West, Gary D.

Patent number: 5914501Abstract: A light-emitting diode assembly incorporates a power shunting element that provides electrical over-stress protection to a light-emitting diode (LED) and prevents damage to the LED from electrostatic discharge (ESD). The power shunting element is coupled in parallel to the LED within the LED assembly and protects the LED by diverting electrical current from the LED and limiting the voltage across the LED to a clamp voltage when a threshold voltage across the LED is exceeded.Type: GrantFiled: August 27, 1998Date of Patent: June 22, 1999Assignee: Hewlett-Packard CompanyInventors: William K.
