Abstract: A clamp-on ultrasonic transducer includes an ultrasound-propagating wedge having a first face and a second face which is inclined to the first face. The clamp-on ultrasonic transducer further includes a first piezoelectric element which is mounted on the second face, and which is directed obliquely at the first face. The wedge has a width, w, between first and second side walls, wherein the width, w, is less than or equal to 10 mm.

Abstract: The present invention relates to a weightlifting device that allows a user to perform multiple exercises with one device. The body of the device is comprised of vertical grips and horizontal grips that allow the user a place to grip during exercise. In addition, the base is comprised of a base support that provides structural integrity to the device. The base is also comprised of a hinge that allows the user to lift the body up or down to perform multiple types of exercises.

Abstract: A method of determining flowrate of a fluid (7) in a pipe is disclosed. The flowrate is determined using a flowmeter having first and second ultrasonic transducers (10; FIG. 8A) separated along the pipe by a given distance (D; FIG. 1) and inclined so that waves in the fluid propagate at a given path angle (?; FIG. 1). For a given inner pipe diameter (d; FIG. 1), there is a given integer number of reflections between the first and second ultrasonic transducers. The method comprises obtaining flow rate measurements using wave packets (18) corresponding to an integer number of reflections which is less than said given number.

Abstract: The present invention relates generally to the field of lane-keeping devices. More specifically, the present invention relates to a device that is primarily comprised of a housing, further comprised of at least one button, at least one laser emitter, a battery, and a light sensor. Further, the device is comprised of a bottom wall, further comprised of at least one fastener. The device is also comprised of a top wall that may be comprised of a solar panel to power the device. Further, the device, via laser emitter, emits a light beam directed out in front of the vehicle onto the roadway. The light beam shown on the roadway allows the driver of the vehicle to know precisely where in the lane their vehicle is located. The device further allows for the light emitter to be changed to encompass an array of different intensities and distances.

Abstract: A patient support including a frame and a mattress supported by the frame. The frame includes a deck support and a deck supporting the mattress.

Abstract: An apparatus is provided for detecting the presence of an obstruction with respect to a height-adjustable bed. The apparatus includes sensors coupled to the bed. At least one of the sensors has an output signal which is variable in response to changes in a weight applied to the support surface. The apparatus also includes a controller having inputs configured to receive the output signals from the sensor or sensors. The controller is configured to monitor the output signals, and to provide an indication of the presence of an obstruction with respect to a change in position of the bed.

Abstract: The present invention provides a hospital bed (10) including a force sensor (24) or scale apparatus configured to detect the weight of a patient (42).
