Abstract: A system, method and apparatus is provided that allows the determination of the reliability of a location determined by a mobile device in response to Navigation System signals. The mobile device sends positioning information derived from the Navigation System signals to a server, the server comparing the positioning information to reference information received from base stations in order to determine its reliability.

Abstract: An electronic device with radio and GNSS receiving capabilities is used to provide a second or further authentication factor to current and future transaction systems. The device's embedded characteristics are combined with GNSS data into a unique identifiable device code. The device can be used initially to put a bank or credit card into a “transaction enabled” mode. The location of the electronic device can be compared to the location from which a request to use the enabled card originates.

Abstract: An electrostatographic printer has a process unit adapted to be removably mounted in a main assembly of an electrostatographic reproducing machine, the process unit including a developement apparatus at which an electrostatic latent image is developed on an imaging member, and a transfer device which causes a developed toner image to be transferred from the moving imaging member to a copy sheet. The development apparatus is contained within a housing of an electrically insulating material, and comprises conductive means adjacent the exit portion of the development apparatus, i.e. the portion from which the imaging member emerges as it moves towards the transfer device. The conductive means includes a conductive coating on the exit portion of the developer housing, and a conductive seal member through which an electrical discharge path is provided.

Abstract: A sealing arrangement for a container in which an auger having vanes is disposed in the chamber thereof for moving particulate material stored therein. A threaded sealing member is adapted to engage the auger vanes so as to be driven along the container on rotation of the auger. The sealing member is mounted slidingly within the container but is restrained from rotating about the auger. On rotating the auger, in one direction, the sealing member moves along the auger to a storage position located beyond the auger vanes.

Abstract: A process unit which can be removably mounted in a main assembly of an electrostatographic copying machine has a housing enclosing an imaging member and, optionally, other processing means such as a development device, a cleaner, and a charge corotron. The transfer corotron, for transferring a toner image from the photoreceptor to a copy sheet is preferably incorporated in the cassette housing. An aperture is present in the housing adjacent corotron so that a copy sheet can enter the unit to have an image transferred thereto from the photoreceptor. A simple resilient cover flap is provided over the aperture which protects the imaging member from contamination, physical damage, and light exposure when the cassette is removed from the main assembly of the copier. The flap is readily displaced as an entering copy sheet bears against it, thus enabling a copy sheet to pass.

Abstract: A cassette for an electrophotographic imaging machine contains a photoreceptor, such as a drum or endless belt photoreceptor and optionally one or more process means, such as a charge corotron, a development device, a transfer corotron and a cleaning device. The photoreceptor belt is loosely held in an open loop, for example by means of belt retaining strips, within a cassette when the cassette is out of the main machine. When the cassette is inserted into a suitably shaped aperture in the main machine, the photoreceptor engages over a plurality of support rollers. At least one of the rollers is movable so as to space it from another roller, thereby tensioning the photoreceptor belt and accurately locating the belt within the main machine. One of the support rollers may also be a drive roller for the belt.

Abstract: Apparatus to be mounted on a cartop for raising a wheelchair from the driver's seat and orienting and engaging the wheelchair for transport on the roof. The supporting base is mounted on the roof with an overlying frame rotatably mounted to the base above the driver's position. The frame is biased to rotate outwardly of the car and a cable is used to raise the wheelchair, engage the frame for rotation and change the attitude of the chair so that it is flat-lying and engaged by the frame for transport.

Abstract: A heated hair straightener has a handle connecting to an electric source and a pair of scissor-like clamp housings pivoted on the handle and having facing coverplate surfaces for clamping and straightening the hair. This combination has an improvement in the heater sub-assembly fitting in one of the housings and formed as a sandwich arrangement including an aluminum coverplate, a copper elongated heater plate forming a first electrode connected to one side of the line and electrically insulated from the coverplate by a thin dielectric film. Plural PTC heater pellets are aligned on the heater plate and held by an insulating locator panel having cut-outs fixing the pellets on the heater plate. A second electrode, formed as a corrugated stainless steel spring plate covers and abuts the PTC pellets and is connected to the other side of the line. Next is a phenolic or ceramic insulator member with a recess for the corrugated spring plate to fit and abut therein.

Abstract: A hair dryer is provided having a first cup-shaped plastic housing with an air inlet and generally tangentially directed outlet to be connected to a hose coupling and thence to a soft bonnet on the head of the user. A sheet metal plate provides a motor and other internal components on one side and a fan on the opposite side with the fan directing air through the outlet. A second plastic cup-shaped housing is provided facing the first and the housing are secured together with the plate between them, the hair dryer having a controlled air heater in the outlet. To this general overall arrangement an improvement comprises a heater formed in the shape of a cone in at least one plane of the outlet and secured to a mounting plate covering the outlet such that, with the housing, the mounting plate and housing form the outlet duct which is faired to form a substantial rectangular-to-round outlet path.

Abstract: A timer control circuit for controlling the ON-OFF operation of a controllable current conducting device, such as an indicator lamp or a semiconductor power device, and for keeping the device in a given operating state over a readily adjustable time interval, that utilizes relatively few components and is of low cost construction. The circuit includes principally resistive-capacitive timing means and transistor switching means, the device being coupled with the transistor switching means which, in addition to selectively connecting the device in and out of the circuit as a function of the timing cycle, feeds back a threshold voltage to the timing means as an integral parameter in determining the time interval.
