Abstract: A hand scraper for griddles and the like has a support (11) for a blade (12) removably secured by a screw (13) projecting forwardly and downwardly from a handgrip (10), and a guard (14) which is conveniently formed of stainless steel rod, is spaced from the underside of the handgrip to afford protection of the fingers and to serve as a stable base for the scraper when not in use. An upwardly extending shield (33) is provided adjacent the blade support (11), to protect the hand from hot fatty debris pushed up over the blade (12).

Abstract: An in vivo image capturing system includes a capsule, and a camera encased within the capsule and configured to capture through a transparent window of the capsule, a view outside the capsule. The system includes a light source enclosed within the capsule and a reflector configured to reflect a ray of light from the light source, away from the camera. Wherever incoming image rays and outgoing illuminating light rays intersect at a common point on any surface of the transparent window, an angle between an outgoing illuminating light ray and a surface normal exceeds an angle between an incoming image ray and the surface normal such that a reflection of the outgoing illuminating light ray from said any surface is not within a field of view (FOV) of the camera.

Abstract: A method is provided for characterizing manufacturing variations in a capsule camera and imperfections in its operating environment to allow images captured by the capsule camera to be compensated for these defects. In one embodiment, a method for characterizing a camera includes: (a) illuminating a field of view of the optical elements under a controlled condition; (b) exposing multiple images onto the image sensor under the controlled condition; (c) extracting parameter values of a model for the image provided on the image sensor from the multiple images; and (d) compensating images taken subsequently in the camera using the parameter values. The objects in the field of view may have a predetermined color, contrast or pattern. In one instance, the controlled condition includes an external light source for illuminating the field of view, and the image sensor is sensitive to a plurality of color components. The field of view may be illuminated at a predetermined light intensity for each of the color components. The camera may include an archival memory for storing the images taken. Alternatively, the camera may include a transmitter for sending images taken to an external depository. The camera may also be associated with an identification, and the transmitter sends the images together with the identification to identify the images sent.

Abstract: An integrated circuit comprises a biasing circuit for maintaining the transconductance of a Gm cell constant. The integrated circuit comprises an on-chip constant voltage source and an on-chip constant current source. The on-chip constant current source has a connection for an external resistance, the value of the external resistance determining the current generated by the constant current source. The biasing circuit comprises means for providing a first fraction (β) of the current generated by the on-chip current source to bias the output of the Gm cell, and means for providing a second fraction (α) of the voltage generated by the on-chip voltage source to bias the input of the Gm cell. The transconductance of the Gm cell is controlled to be equal to the ratio of said fraction of the current generated by the on-chip current source to said fraction of the voltage generated by the on-chip voltage source.

Abstract: An optical transmitter/transceiver that includes a gain medium having a sufficiently highly reflective surface at one end, a sufficiently anti-reflective surface at another opposite end, and an attachable/detachable wavelength-selective reflection mechanism which when coupled to the gain medium effectively becomes part of a laser cavity. A transmitter/transceiver module that includes a number of these optical transmitter/transceivers provides a multi-wavelength output source, depending upon the attachable/detachable wavelength-selective reflection mechanism chosen for a particular transmitter/transceiver.
