US Patent:

7473020, Jan 6, 2009

Filed:

Jul 7, 2006

Appl. No.:

11/483026

Inventors:

William Pickering - Brooklyn NY, US

International Classification:

F21V 7/04

US Classification:

362612, 362252, 362559

Abstract:

A light emitting diode (LED) display, including: drive circuitry; a control processor; a frame including two edges; multiple cables extending rigidly between the two edges of the frame; and at least one pixel module coupled to each cable. Each cable includes a power wire coupled to the drive circuitry, a ground wire, and at least one data bus wire coupled to the control circuitry. Each pixel module includes: a power electrode coupled to the power wire of the coupled cable; a ground electrode coupled to the ground wire of the coupled cable; a bus electrode coupled to the data bus wire of the coupled cable; an LED light source; and pixel control circuitry coupled to the electrodes and the LED light source. The pixel control circuitry is adapted to drive the LED light source with a drive current based on a control signal received from bus electrode.

International Classification:

A61B 500

US Classification:

600490

Abstract:

A hybrid sphygmomanometer comprises: (a) an arm cuff with an inflatable air bladder; (b) a pumping device for inflating the air bladder; (c) a manually controlled air outlet valve for deflating the air bladder; (d) an air pressure transducer operative to receive the pressure in the air bladder of the arm cuff and to produce an electrical signal representing this pressure; (e) a manually operated switch for generating systolic and diastolic interrupt signals; (f) a first electronic display for displaying the instantaneous pressure in the air bladder in the form of a bar graph; (g) a second electronic display for displaying systolic and diastolic pressures; and (h) an electrical circuit connected to the pressure transducer and to the button for controlling said first and second display. The first display, for displaying the instantaneous pressure in the air bladder, is a simulated mercury column. The electrical circuit provides an output of digital signals, representing the systolic and diastolic pressures, for use by a programmed digital computer for storage and processing.

International Classification:

H01L 33/62
H01L 33/60

Abstract:

A flip-chip package comprising: (a) a lead frame; (b) a flip-chip LED defining a die footprint and having RDL contacts, the RDL contacts being configured to facilitate flip-chip mounting of the LED on the lead frame, each of the RDL contacts having a footprint greater than 20% of the die footprint; and (c) at least one bonding layer disposed between the RDL contacts and the lead frame package.
