  • Patent number: 11860027
    Abstract: A weigh head apparatus (102) for cooperation with a data processing unit for use in livestock weighing. The weigh head apparatus is inexpensive, easy to upgrade and has low maintenance costs. The weight head apparatus has: a signal converting module (106) operable to convert one or more analogue load signal into a plurality of digital load values; and a data transmitting module (108) operable to transmit a stream of the digital load values over a wireless connection to the data processing unit. The stream is a real-time stream and the digital load values are raw instantaneous analogue-to-digital converter output values. A command receiving module (109) is configured to receive a transmit-stream command from the data processing unit, wherein the data transmitting module (108) is operable to transmit the stream of the digital load values in response to the received transmit-stream command.

  • Publication number: 20070280513
    Abstract: An optical fingerprinting method extracts high quality latent fingerprints from a surface without any invasive chemical or physical contact with the examined object, and requires no cooperation of the subject. Rather than employing extraneous material, the optical properties of the latent fingerprint are used to generate one or more images with sufficient contrast to distinguish the latent fingerprint or some other deformation in the surface. The system includes a light source oriented to apply light at an angle of incidence to the surface at the position to be examined for the latent fingerprint or deformation, a camera oriented to receive light specularly and diffusely reflected from the surface and/or by the fingerprint or deformation on the surface, and a processor that performs the computation for digital contrast enhancement and/or reprojection of the recovered fingerprint image to a frontal view if necessary.

  • Patent number: 4046454
    Abstract: A thin chip having parallel, evenly spaced optical fiber-receiving grooves on at least one side forms the basic building block for a certain prior art multilayer optical fiber connector. The end arrays of fiber groups assembled within stacks of such chips are substantially identical in spacing, thus enabling a gang splice to be achieved with a simple abutment of the two end arrays. The present disclosure achieves vertical spacing between layers, as well as horizontal fiber spacing in a given layer, by including in the base of each chip a thin layer of compliant material to urge the fibers housed in the adjacent chip into their respective grooves. The compliance is sufficient to permit vertically adjacent chips to contact each other rather than to float atop fibers. The splice array additionally uses a key chip which rests upon a vertical reference surface with one end contacting a horizontal reference surface. These surfaces may form part of the permanent splice.

  • Patent number: 3930636
    Abstract: A ball valve having a seating ring held in a recess in the valve bore by threaded portions of the ring and bore such that, when the ring is in position, the threaded portion on it has passed right through the threaded portion of the bore, there being a radial expansion gap between part of the ring and the recess.
