Publication number: 20140314573Abstract: An individual blade control system (IBCS) for a rotor system having a rotor hub is provided including a plurality of blade cuffs mounted to the rotor hub. Each blade cuff is configured to receive a rotor blade and rotate about a blade axis. A plurality of electrical actuators is mounted to the rotor hub adjacent at least one of the plurality of blade cuffs. Each electrical actuator is configured to rotate about an actuator axis. The plurality of blade axes and the plurality of actuator axes are arranged in a plane. Each electrical actuator is coupled to an adjacent blade cuff such that rotation of one of the plurality of electrical actuators causes a proportional rotation of one of the blade cuffs.Type: ApplicationFiled: April 22, 2013Publication date: October 23, 2014Applicant: Sikorsky Aircraft CorporationInventors: Bryan D.

Patent number: 5898161Abstract: A wrist-mounted terminal for use in electro-optically reading bar code symbols, includes a main body having a display, and a strap for securing the body on and around a wrist of an operator. The terminal includes a detector for detecting light reflected off a symbol. A keypad is mounted on the body for movement between a concealed position in which manually depressible keys are hidden by the body, and an exposed position in which the keys are accessible. The keypad is preferably slidingly received within the body, or hinged to the body.Type: GrantFiled: February 25, 1997Date of Patent: April 27, 1999Assignee: Symbol Technologies, Inc.Inventors: Joseph DeVita, Joseph Katz, Don Searle, Mitchell Maiman, Jay McDonald, John Potter, Gonzaga Joseph Chow

Patent number: 5801371Abstract: A system for reading indicia such as bar code symbols having a scanner for generating a scanning light beam directed toward a symbol to be read; a first actuator manually displaceable from a first position to a second position for producing a first light beam for aiming or positioning the reader, and a second actuator manually displaceable from a first position to a second position for initiating a scanning beam pattern for reading the symbol. The actuators are independently operative of each other. A detector receives the reflected light from the symbol and produces electrical signals corresponding to data represented by the symbol. A graphical user interface with icons simplifies system control functions.Type: GrantFiled: July 24, 1996Date of Patent: September 1, 1998Assignee: Symbol Technologies, Inc.Inventors: Joel Kahn, Richard Isaac, Joseph DeVita, Daniel R.

Patent number: 5763865Abstract: An electro-optical system for reading bar code symbols includes a reader module and a terminal module releasably interconnected to each other. The reader module includes a manually actuatable actuator to initiate the reading. Reading is initiated either when the modules are disconnected, or when the modules are interconnected, by manually actuating the actuator in both cases. A keyboard may be provided on either module to facilitate data entry.Type: GrantFiled: April 1, 1996Date of Patent: June 9, 1998Assignee: Symbol Technologies, Inc.Inventors: Philip W.

Patent number: 5610387Abstract: An optical scanning system for reading indicia of differing light reflectivity has an optical scan module including a light emitter for emitting light onto the indicia and a light detector for detecting the reflection of light from the indicia. The scan module is adapted to be mounted on at least one finger of a user. A first peripheral module has a receiver for receiving a first signal corresponding to the detected reflection of light from the optical scan module. The first peripheral module is adapted to be mounted on an arm or wrist of the user. A second peripheral module includes a receiver for receiving a second signal corresponding to the first signal from the first peripheral module by radio frequency transmission. According to other aspects of the invention, the light detector is located in a housing separate and apart from the optical scan module.Type: GrantFiled: April 24, 1996Date of Patent: March 11, 1997Assignee: Symbol Technologies, Inc.Inventors: Simon Bard, Brian Viscount, Joseph Katz, Joseph DeVita, Anthony Fama, Paul Poloniewicz, Anthony Biuso, Laura Wilson, Gary G.

Patent number: 4325118Abstract: The invention is used in a computer system to buffer the transfer of program portions from a system having a first bus width to instruction processing logic having a second bus width. An instruction register receives program portions via a system bus from the program memory. A state register stores a code specifying the action to be taken to transfer the next program portion from the instruction register to the instruction processing logic. Control logic, upon receiving a request for the next program portion from the instruction processing logic, inspects the state register to determine whether the next program portion in sequence should be retrieved from the memory and stored in the instruction register. In addition, the control logic transfers the appropriate program portion to the instruction processing logic, and updates the state register code in preparation for the next request from the instruction processing logic.Type: GrantFiled: March 3, 1980Date of Patent: April 13, 1982Assignee: Western Digital CorporationInventors: Joseph DeVita, Brian Pirzadeh
