Publication number: 20110004076Abstract: A system and method for communicating with a medical implant is disclosed. The system (10,210,310,410) includes on-board electronics, a signal generator (15,215), an amplifier (16,216), a coil (14,214), a receiver (22,222), and a processor (20,220). The on-board electronics (100, 110) include a power harvester, a sensor, a microprocessor, and a data transmitter. The signal generator (15,215) generates a first signal, the amplifier (16,216) amplifies the first signal, the coil (14,214) transmits the amplified signal, the power harvester receives the first signal and transmits a data packet (18,218) containing data, the receiver (22,222) receives the data packet (18,218), and the processor (20,220) either processes the data or sends the data to a data storage device.Type: ApplicationFiled: January 30, 2009Publication date: January 6, 2011Applicant: SMITH & NEPHEW, INC.Inventors: Sied W.

Patent number: 6816281Abstract: A printing device is described, predominantly for printing labels on a tape. The printing device has a display and input means for inputting characters to be printed by the printing device. Using the input means, a cursor on the display can be controlled. The printing device has a label memory which comprises a storage portion having a plurality of storage sections. The display is operable to display a plurality of label access elements each of which represents a respective storage section in the storage portion of the memory. The cursor is used to access a selected storage section of the memory associated with the label access element identified by the cursor position. A method of storage label data in a label memory using this principle is also described.Type: GrantFiled: July 28, 2000Date of Patent: November 9, 2004Assignee: EsselteInventors: Clive Lawrence Ayling, Michel Woodman, David Roger Tegerdine, Geoffrey Stuart Howe
