Abstract: A system for motion analysis of a subject includes two or more sensor units that are attachable at respective attachment points of the subject to detect motion of the attachment points relative to each other, each sensor unit including a time-of-flight (TOF) ranging sensor in communication with at least one processor. The at least one processor is configured to: cause the sensor units to execute a two-way ranging protocol at a succession of times, said two-way ranging protocol including transmission of one or more signals from, and reception of one or more signals at, said TOF ranging sensors, to determine TOF distance data indicative of one or more respective distances between the sensor units at respective times; and determine, from at least the TOF distance data, one or more motion metrics.

Abstract: Devices, systems, and methods herein relate to electromyography (EMG) that may be used in diagnostic and/or therapeutic applications, including but not limited to electrophysiological study of muscles in the body relating to neuromuscular function and/or disorders. Sensor assemblies and methods are described herein for non-invasively generating an EMG signal corresponding to muscle tissue where the sensor may be positioned directly on a surface of the muscle tissue including any associated membrane (e.g., mucosal, endothelial, synovial) overlying the muscle tissue. A sensor assembly may include one or more pairs of closely spaced, atraumatic electrodes in a bipolar or multipolar configuration. The first and second electrodes may be applied against a surface of muscle tissue (that may include a membrane overlying the muscle) and receive electrical activity signal data corresponding to an electrical potential difference of the portion of muscle between the electrodes.

Abstract: An automotive headlamp (10) having a solid-state light source (14) and a reflector (16) having a light collecting region (18) adapted to receive a first portion of light emitted by the solid-state light source (14) and reflect the first portion of light in a first illumination pattern. The automotive headlamp (10) further includes a light guide assembly (22) adapted to receive a second portion of light emitted by the solid-state light source (14) and redirect the second portion of light in a second illumination pattern.

Abstract: A lamp apparatus (14) includes a heat sink (28), a heat conductive post (26) having a plurality of faces (36), one or more light engines (30) coupled to each of a plurality of faces (36), a connector (32) to provide power to the light engine (30) when electrically coupled to a lamp socket, and a grommet (34). The grommet (34) is secured to and extends around a perimeter of the heat conductive post (26) and includes a radial groove (48) receiving a rim (21) of an opening (20) of a reflector (12) such that a first and a second portion (50, 51) of the grommet (34) extend beyond the rim (21) and over a portion of an interior and an exterior surface (23, 25) of the reflector (12) to secure the lamp apparatus (14) to the opening (20) of the reflector (12).

Abstract: A method of inserting a multi-lumen catheter assembly. First, an incision is made near the area to be catheterized. The proximal portion of the multi-lumen catheter tube is then inserted into the area to be catheterized. A subcutaneous tunnel is created, and the first end of the tunnel is near the incision. The catheter tube is then routed through the subcutaneous tunnel and pulled tube through a second end of the subcutaneous tunnel. The hub body is then securely attached to the catheter tube by connecting the connection cover to the hub body by threaded engagement. In a preferred embodiment the hub body is attached to the catheter tube by backfitting the connection cover over the catheter tube. A compression sleeve is also backfit over the catheter tube. The cannulae of the hub body are inserted into the lumens of the catheter tube to create fluid communication therebetween.

Abstract: A method for modeling an investment significant parameter of a financial instrument, using a computer. At least one series of historical bid prices of the financial instrument or historical ask prices of the financial instrument is provided. A financial model type that has at least one variable parameter is selected. The variable parameter(s) of the selected financial model type is initialized. The series of historical bid prices and/or historical ask prices is applied to the initialized financial model type to estimate the variable parameter(s). The resulting model of the financial instrument may be used to predict future values of the investment significant parameter of the financial instrument. These predicted future values may be used to determine whether to perform automated trades of the financial instrument.

Abstract: The present invention is a multi-lumen catheter assembly having a selectively attachable hub including a multi-lumen catheter tube that has a proximal portion and a distal portion and a hub assembly that has a proximal portion and a distal portion, whereby the distal portion of the catheter tube is selectively attachable to the proximal portion of the hub assembly after subcutaneous insertion of the proximal portion of the catheter tube into a patient.

Abstract: A wind-propelled vehicle, particularly a multi-hulled sailing vessel, in which instead of mast, the upper spar (14) of the sail (13) is supported from a carrier (13) which moves athwart the vessel in a track in the form of an arch (16).

Abstract: An electric fan and patio umbrella combination. The device uses an electric fan mounted as a integral part of a patio umbrella. The umbrella fabric is open at the top exposing the fan to direct air from above. This direct exposure to an air source is what gives the device its high volume of air flow. Since the fan support structure is a part of the upper umbrella support structure, the umbrella can be raised or lowered around the fan blades without the need to hinge the blades up or down, therefore allowing the umbrella to fold. This is accomplished by the use of an upper support ring that provides an outer hinge point for the upper umbrella rib supports. The fan blades block most sunlight from entering the fabric opening at the top, however an additional fabric cover is provided that may be pulled over the opening if desired.

Abstract: A device for smoking combustible materials includes a tubular body member constructed entirely of heat-resistant glass material. The device has an internal bore with an integrally formed venturi that separates the bore into a smoke chamber and a loading chamber. A method of forming the device includes providing a tubular body member constructed entirely from a heat-resistant glass material; forming a constricted passage in a bore of the tubular body member by applying heat to a predetermined location on the tubular body member until the glass material expands into the bore at the predetermined location; and smoothing the outer surface of the tubular body member at the predetermined location.
