Title: Radiotelephones having contact-sensitive user interfaces and methods of operating same
Inventor: THORNTON CURTIS WAYNE
IPC: H04M1/72469
Filed: 1998-12-18
Abstract: The present invention provides radiotelephones and methods of operation thereof in which control of a radiotelephone's display and/or radiotelephone communications transceiver is effected using a contact-sensitive transducer such as a resistive or capacitive touch strip mounted on the radiotelephone. The contact-sensitive transducer produces an output signal that characterizes contact, e.g., contact of an object such as a user's finger, with a surface of the transducer. The output signal may be processed by a controller to control display of information on the display and to initiate actions associated with displayed items. For example, the contact-sensitive transducer may be used to control display of graphical objects such as rows or columns on the display, and initiation of functions associated with the graphical objects. Preferably, the contact--sensitive transducer comprises an elongate strip and produces an output signal that characterizes contact with the strip along its elongate axis. In one embodiment, two of such elongate strips are mounted on respective sides of the radiotelephone. In another embodiment, an elongate strip is mounted on a front face of the radiotelephone.

Title: Micromechanical potentiometric sensors
Inventor: THUNDAT THOMAS G
IPC: G01Q60/42
Filed: 1999-03-16
Abstract: A microcantilever potentiometric sensor (1) utilized for detecting and measuring physical and chemical parameters in a sample of media is described.  The microcantilevered spring element (3) includes at least one chemical coating (7) on a coated region, that accumulates a surface charge in response to hydrogen ions, redox potential, or ion concentrations in a sample of the media being monitored. The accumulation of surface charge on one surface of the microcantilever (3), with a differing surface charge on an opposing surface, creates a mechanical stress and a deflection of the spring element (3). One of a multitude of deflection detection methods may include the use of a laser light source (17) focused on the microcantilever (3), with a photo-sensitive detector (19) receiving reflected laser impulses. The microcantilevered spring element (3) is approximately 1 to 100 micro-meters long, approximately 1 to 50 micro-meters wide, and approximately 0.3 to 3.0 micro-meters thick. An accuracy of detection of deflections of the cantilever (3) is provided in the range of 0.01 nanometers of deflection. The microcantilever apparatus (1) and a method of detection of parameters require only microliters of a sample to be placed on, or near the spring element (3) surface. The method is extremely sensitive to the detection of the parameters to be measured.

Title: N x m digitally programmable optical routing switch
Inventor: LIU JIAN-YU
IPC: H04B10/43
Filed: 1999-04-16
Abstract: An optical routing switch provides polarization-independent, low-crosstalk between any input port (500, 501) and any output port over a wide operating range of temperatures and wavelengths. Optical signals at each input (500, 501) are spatially decomposed into two orthogonally-polarized beams by a first polarization-dependent routing element (30). This beams are routed through optical switches, which each includes: (1) a switchably controlled polarization rotator (100) so that both of the emergent beams are either horizontally or vertically polarized based on the control state of the device;  and (2) a polarization-dependent routing element which routes the beams based on polarization. These beams are then input to an array of polarization rotators that change the polarization of at least one of the light beams, so that the two beams are orthogonally polarized. A polarization-dependent routing element (60) intercepts the two orthogonally-polarized beams and recombines them to exit at the selected output port.

Abstract: The present invention provides methods for enhanced detection of biological response profiles. In particular, the methods of this invention allow for the detection of biological response patterns, such as gene expression patterns, in response to different drug treatments. The methods of the invention also allow the determination of a "consensus profile" which describes a particular class or type of biological response. In certain embodiments the consensus profile may describe the biological response of a particular group or class of drugs. In other embodiments, the consensus profile may describe an "ideal"  biological response such as one associated with a desired therapeutic effect.  The methods of the present invention also allow for the comparison of different biological responses. Thus, the methods of the invention may be used, e.g., to identify and/or study new drugs.
