Abstract: A low-profile, backlit panel assembly and a controller for displaying images and/or data within a passenger compartment of a vehicle are provided. The assembly includes a substrate panel perforated with a two-dimensional array of closely-spaced holes. The panel is configured to be attached to a support structure of the vehicle. The assembly further includes a plurality of semiconductor-based, lighting devices supported at a back surface of the panel. Each of the lighting devices includes at least one lighting element. Each of the lighting elements is individually addressable by the controller to control luminous intensity of the light emitted by the at least one lighting element. Each of the lighting devices is aligned with one of the holes so that light emitted by each of the lighting devices travels through its hole to the passenger compartment in the form of a pixel of a two-dimensional image.

Abstract: The present invention relates to several methods to detect gram positive mastitis pathogens in a small sample of bovine milk by luminescence using a combination of specific reagents giving a “cow side” “in-stall” indication of the presence or absence of gram positive mastitis pathogens within a short period of time.

Abstract: An inkjet printer is described. The inkjet printer has a substrate holder assembly that includes a base member having a long axis in a first direction and a short axis in a second direction perpendicular to the first direction; a contact member coupled to the base member, the contact member having a long axis in the first direction and a short axis in the second direction; a holder carriage coupled to the base member; a linear extender coupled between the base member and the contact member and extending in a third direction intersecting with the first direction and the second direction from the base member toward the contact member; and a flex member coupled to the base member, extending in the second direction between the linear extender and the contact member, and having a flex direction in a direction perpendicular to the first direction and the second direction.

Abstract: A controller to control semiconductor-based lighting devices of a display assembly in a vehicle so that the display assembly displays computer-generated images within a passenger compartment of the vehicle is provided. The controller includes a power inlet terminal adapted to receive electrical power from a vehicle power source and a command input terminal adapted to receive display command signals from a remote electronic control unit through a vehicle-based bus. The controller also includes electronic circuitry including a computer coupled to the terminals to receive the command signals and the electrical power and supplies the electrical power and control data signals generated by the circuitry over an internal bus to a control circuit of each lighting device to individually control multi-colored lighting elements of the lighting devices based on the command signals to display the images in the form of pixels at the front the assembly.

Abstract: A low-profile display assembly for a vehicle is provided. The assembly includes a substrate having a plurality of holes extending completely therethrough. The assembly further includes at least one lighting display panel and a plurality of semiconductor-based, lighting devices supported and mounted thereon. Each of the lighting devices includes multicolored lighting elements. Each of the lighting elements is individually addressable to control the luminous intensity of the lighting elements. Each of the lighting devices is aligned with one of the holes so that light emitted by each of the lighting devices travels through its hole to the front of the assembly in the form of a pixel of a computer-generated image. Color of light emitted by each of the lighting devices is controlled by controlling the luminous intensity of light emitted by its lighting elements.

Abstract: A payment terminal can have a secured test mode. Interfaces of the payment terminal may be secured via various techniques. Self-test input touch inputs may be provided at a user interface to initiate device self-tests. The payment terminal may perform the self-tests, and generate a machine-readable output including device information and results from the self-tests. The payment terminal may display the machine-readable output for scanning by test equipment.

Abstract: A point-of-sale (POS) device includes a processor, a universal serial bus (USB) hub, two switches, and an external connector that connects the POS device to a secondary device with its own second processor. In a primary mode, the processor is connected to a host connector of the USB hub and the secondary device is connected to a first peripheral connector of the USB hub via the external connector. In a secondary mode, the processor is connected to the first peripheral connector of the USB hub and the secondary device is connected to the host connector of the USB hub via the external connector. The processor controls the switch from the primary mode to the secondary mode, and vice versa, by transmitting control signals to control pins of the two switches, and optionally by transmitting a reset signal to a reset pin of the USB hub.

Abstract: A flow measuring device for measuring flow of a fluid. A housing has a passage which extends between an inlet and an outlet. A shaft is disposed within the housing and is rotatable about a central axis. A flow detector is mounted on the shaft and disposed at least partially within the passage. The flow detector includes a rotatable, generally cylindrical body that rotates about a central axis as the fluid flows. A magnet is disposed within the housing such that the central axis extends through it, and is configured to rotate simultaneously with the body about the central axis. A magnetic encoder is disposed within the housing and configured to sense rotation of the magnet as the flow detector angularly displaces about the central axis so as to detect angular displacement of the flow detector.

Abstract: Methods and systems for determining lubrication flow dispensed to lubrication points. Lubricant delivery is determined based upon the difference between volume measurements detected as the lubricant is delivered to the lubrication points, and volume measurements detected as the lubricant is vented after delivery. A flow sensor in the lubricant supply line measures lubricant delivered and lubricant vented and a controller determines the amount dispensed based upon the difference between the delivered and vented measurements.
