Title: Contact arrangement for detachably attaching an electric component, especially an integrated circuit to a printed circuit board
Inventor: AFFOLTER HUGO
IPC: H05K7/10
Filed: 1996-05-10
Abstract: The contact arrangement is a connector block for detachably fastening an electrical component, particularly in integrated circuit having a plurality of terminal contacts disposed in a ball grid array (BGA), in a column grid array (CGA), in a land grid array (LGA) or of the flip-chip type to a printed circuit board. In a support part, a number of contact pins are disposed in a grid in bores. The contact pins project from the bore on the sides facing the printed circuit board and are surface-mounted together with contact areas of the printed circuit board. A free end region of each bore is intended for guiding the substantially dome-shaped terminal contacts. Between the end of a contact pin and a terminal contact there is a space bridged for establishing an electrical connection with a contact element, for example an axially compressible coil spring. By means of several holding-down elements disposed peripherally to the integrated circuit, the integrated circuit is pressed down upon the support part. Even with a plurality of terminal contacts, a faultless electrical contact is achievable between the terminal contacts and the associated contact pins with a holding-down force which is relatively small. This particularly because with the contact arrangement according to the invention, no axially acting frictional forces need be overcome for establishing the contact.

Abstract: A balloon (12) for use in compressing cancellous bone and marrow (also known as medullary bone or trabecular bone) against the inner cortex of bones whether the bones are fractured or not. The balloon comprises an inflatable, non-expandable balloon body for insertion into said bone. The body has a shape and size to compress at least a portion of the cancellous bone to form a cavity in the cancellous bone and to restore the original position of the outer cortical bone, if fractured or collapsed. The balloon is prevented from applying excessive pressure to the outer cortical bone. The wall or walls of the balloon are such that proper inflation of the balloon body is achieved to provide for optimum compression of all the bone marrow. The balloon is able to be folded so that it can be inserted quickly into a bone. The balloon can be made to have a suction catheter (16). It can also be coated with therapeutic substances. The main purpose of the balloon is the forming or enlarging of a cavity or passage in a bone, especially in, but not limited to, vertebral bodies. Another important purpose is to deliver therapeutic substances to bone in an improved way.

Title: Fluorescence lifetime-based imaging and spectroscopy in tissues and other random media
Inventor: PAITHANKAR DILIP Y
IPC: A61B10/00
Filed: 1996-08-23
Abstract: A system and method non-invasive biomedical optical imaging and spectroscopy with low-level light is described. The technique consists of a modulated light source (120) coupled to tissue (100) of a patient to introduce excitation light. Fluorescent light emitted in response to the excitation light is detected with sensor (148). The AC intensity and phase of the excitation and detected fluorescent light is provided to a processor (160) operatively coupled to sensor (148). Processor (160) employs the measured re-emission kinetics of excitation and fluorescent light to "map" the spatial variation of one or more fluorescence characteristics of the tissue (100). The fluorescence characteristic may be provided by exogenous contract agents, endogenous fluorophores, or both.      The variations is determined by solving frequency domain diffusion equations at a number of designated points in the tissue as part of a recursive estimation algorithm. Processor (160) generates an imaging signal in accordance with the spatial variation of the fluorescence characteristic for provision to an output device (164).      The output device (164) displays an image corresponding spatial variation of the fluorescence characteristic which corresponds to tissue (100) to aid in the detection and diagnosis of disease.
