Abstract: A mobile, hand-held communication device with a display screen and a camera is programmed to perform a postural screening method. An image of a patient is acquired on the display screen having an array of pixels. A pixel to distance ratio of the displayed image is determined. A postural displacement of the patient in the displayed image is calculated using the determined ratio. A gyroscope, accelerometer and/or a level of the device is used to level the camera before capturing the image with the camera. Reference lines are overlaid on the display screen and the image to enable alignment of the image. A reference line on the display screen is used for normalizing a known distance in the aligned image to a reference distance of a known number of pixels on the screen for determining the ratio.

Abstract: The present disclosure generally pertains to systems and methods for releasing children from child safety seats. A child safety seat is secured to a vehicle seat, and a child is secured to the child safety seat. A single release action enables the child to be removed from the child safety seat thereby facilitating removal of the child from the child safety seat and reducing the time required to remove the child from the child safety seat.

Abstract: A door closer assembly is provided, including a valve regulating an amount of hydraulic fluid that flows through the valve. The amount of hydraulic fluid flowing through the valve controls a force generated by the door closer assembly on a door. A first sensor measures an angular position of the door, and a second sensor measures an angular position of the valve. The angular position of the valve determines the amount of hydraulic fluid flowing through the valve. A controller controls the adjustment of the valve based on the angular position of the door and the angular position of the valve.

Abstract: A laser scanning system that employs synchronous time-division-multiplexed laser scanning operations and signal processing operations (for bar code detection). A plurality of successive non-overlapping time slots are defined and logically assigned to a unique laser scanning beam and corresponding photosensor. During a given time slot, the laser scanning beam logically assigned thereto is selectively generated (or selectively projected) into the scanning volume while generation (or projection) of the other laser scanning beam is disabled. Moreover, during the given time slot, the photosensor logically assigned thereto is operably coupled to signal processing circuitry that performs bar code detection operations on the data signals derived therefrom while the other photosensor is operably decoupled from such signal processing circuitry.

Abstract: A computer-readable medium is provided, comprising a set of instructions for execution by a processor of a computing device at a subscriber premises. The processor is operable to execute a software application that enables the computing device to participate in a media connection over a data network. Execution of the set of instructions by the processor causes the computing device to execute a method that includes performing a connectivity test over a test connection established through a gateway at the subscriber premises and over the data network; and prior to performing a connectivity test, provisioning the gateway to enable establishment of said test connection.

Abstract: A method and apparatus comprising four co-planar metallic plates, two for transmission and two for reception, in which each pair of co-planer metallic plates of overall length L are disposed either in direct contact with the earth or are elevated a distance Z above the earth to form a capacitor comprising the metallic plates and the earth if Z=0 or if Z>0, the metallic plates, the air space and the earth. A short voltage or current pulse is applied to this capacitor via a transformer in which the magnetic flux current is adjusted to provide a pulse of the desired frequency composition in the air-earth propagation medium. This results in a frequency controlled pulse of electromagnetic radiation into the targeted subterranean geology at frequencies <500 KHZ.
