  • Publication number: 20190332835
    Abstract: Methods, systems and apparatus for detecting object location and generating alerts are disclosed herein. An example disclosed method includes determining an assigned area for an object being handled by a loader; detecting a first location of the loader; determining whether the first location corresponds to the assigned area for the object; and in response to the first location not corresponding to the assigned area for the object, generating a first output indicative of a difference between the first location and the assigned area for the object.

  • Publication number: 20110070379
    Abstract: A light stabiliser AS comprising a surface-active or amphiphilic part A which leads to migration of the stabiliser to the surface of a material during the process of formation of a surface, and solidification of the material, and a stabilising part S which is the photochemically active ingredient and transforms the energy of the incident light to vibrational or heat energy that is dissipated within the material, characterised in that both parts are connected by a chemical bond in the form of a single or multiple bond or of an at least divalent bridging group

  • Publication number: 20050102701
    Abstract: An attention parental switch system of video/audio device includes a button group, a function selection circuit, a microprocessor, an input control circuit, a central processor member, an audio control circuit and a video control circuit. The button group includes a change-over button and other button, such as volume button, power button. The input control circuit processes the signal coming from the button group and produces an output signal. The central processor member includes a central processor, ROM and RAM, program that the central processor runs and attention information data are stored in the ROM in advance. When a user pushes the change-over button, the central processor can cut off the audio input, at the same time, the central processor processes the attention information data and converts it into video signal to be outputting; the user pushes the change-over button again, audio signal will output again, and the central processor processes stops processing the attention information data.

  • Patent number: 6851200
    Abstract: A reflecting lighted level (10) for facilitating leveling of an object, the reflecting lighted level (10) broadly comprising a generally frustoconically-shaped vial (12) having first and second exterior surfaces (22,24) and an internal angled reflecting surface (26); a light source (14) for emitting light; a light tube (16) for focusing or concentrating the emitted light towards the vial (12); a base (18) for supporting the vial (12); and a power source (20) for powering the light source (14). The internal angled reflecting surface (26) within the vial (12) is positioned at a generally 45° angle for reflecting light. The light source (14), a light emitting diode (“LED”), is centrally positioned relative to the vial (12). The light tube (16) is positioned proximate to the first exterior surface (22) of the vial (12), such that the light tube (16) is positioned between the light source (14) and the vial (12). The light source (14) is then partially positioned within the light tube (14).
