Abstract: An optical fiber made up of a core for propagating the light and a clad covering the core for confining the light propagated in the core. The optical fiber has a tapering protrusion at the apex for entrance and exiting of light. The optical fiber is used in a photon scanning tunneling microscope detecting the evanescent light localized in an area smaller in size than the wavelength of light on the surface of a sample as an optical probe disposed in proximity to the surface of the sample for scattering the evanescent light for detecting the scattered light. The optical fiber is optically coupled to an optical waveguide for constituting an optically coupled element. With this optically coupled element, a protrusion of the optical fiber operates as a collection unit for collecting the light propagated in the core. The light collected by the protrusion enters the optical waveguide. <IMAGE>

Abstract: A bootstrapped audio line receiver that receives a differential-mode input signal from first and second differential lines and outputs a single-ended signal on an output line. The line receiver includes a differential amplifier and an input amplifier having differential output terminals and differential input terminals. The input amplifier is connected between the differential lines and the differential amplifier. The input amplifier provides a dc current path to a ground terminal while maintaining a high input impedance to ac signals at audio frequencies. The input amplifier also includes an rf filter that removes rf noise without adversely affecting the line receiver's common-mode noise rejection at audio frequencies. In one embodiment, the input amplifier includes two operational amplifiers connected for unity gain and having two bias resistors connected in series between each input terminals of the input amplifier and a ground terminal. A capacitor is connected from the output of each operational amplifier to a node between each set of series connected bias resistors and prevents the low impedance of the bias resistors from significantly degrading the line receiver's common-mode rejection ratio. Thus, the line receiver tolerates a wide range of balanced and unbalanced source impedances with a minimal deterioration of the line receiver's common-mode rejection ratio.

Abstract: A communications network having a number of routers, a number of base stations and a number of mobile units maintains communications with the mobile units by assigning a unique address known to the routing entities of the network to each mobile unit. By including the mobile units unique address in topology updates of the network, the location of the mobile unit at any time is made known to all routers of the network. That is, once a mobile unit moves into a domain of a new access point and establishes a new link with the new access point, it uses the topology update mechanism of the network to make its new location known to all routers. Once a router of the network receives topology update information specific to the mobile unit's new location, it updates its routing table such that packets destined to the mobile unit are routed in a path which terminates at the mobile unit and contains its new access point.

Such prodrugs are relatively non-toxic and can be used in cancer treatment. They can be selectively activated at the tumor site by the action of endogeneous enzymes or targeted enzymes, or via a non-enzymatic process. The enzyme is preferably  beta -glucuronidase,  beta -glucosidase or beta -galactosidase.

Abstract: A low noise amplifier structure based on a Differential Difference Amplifier (DDA1) having a differential output (outp, outn) and two differential pairs of input terminals (N1, P1; N2, P2). The input signal (VIN) is applied to terminals (N2, P1) which belong to different differential pairs. In this way, none of the differential pairs receives a high input signal, and hence none of them cause unacceptable harmonic distortion. The dynamic input range is thus high. The gain of the structure is determined by a resistive circuit (R2a, R2a'; R2b, R2b') coupled to the remaining terminals (N1, P2) of the differential pairs. The common mode of these remaining terminals (N1, P2) is, independently from the output common mode, biased at the input common mode via a common mode feedback circuit (DDA2; GL1, GH1, GH3, R2a, R2a'; GL2, GH2, GH4, R2b, R2b') based on a second differential difference amplifier (DDA2). Some switching elements (GL1, GH1, GH3; GL2, GH2, GH4) allow the gain to be programmed and prevent the common mode feedback circuit from injecting differential noise if the gain is high. The structure is adapted to amplify signals of 1 Vpp with acceptably low distortion. <IMAGE>

Abstract: A selectable field of view device is disclosed which is capable of expanding the relatively narrow field of view of a camera to nearly spherical proportions. The device includes a pair of signal diverters, such as mirrors in the case of light signals, each mirror's reflective surface being parallel to the other's reflective surface, and each mirror being independently rotatable about an X-axis and a Y-axis respectively. Each axis passes through a central portion of its respective mirror with the Y-axis intersecting the X-axis and the X-axis being relatively centered within the field of view of the sensor. The mirrors may be driven by one or more motors. When one motor is used, a brake and idler arrangement provides for rotation of one mirror while the other mirror remains stationary relative to its respective axis. In addition, when one motor is used, the sensor is rotated by the motor via a drive belt such that the sensor rotates the same amount as does the mirror being rotated.
