Abstract: Subject matter includes a method comprising: generating a first electrical signal having a time-varying waveform; generating a second electrical signal having a time-varying waveform, wherein a sum of the first electrical signal and the second electrical signal comprises a target electrical signal having a waveform to generate substantial motor movement of the one or more muscles in the patient; and applying the first electrical signal via a first electrode and the second electrical signal via a second electrode to a particular location on the patient, wherein the first electrode and the second electrode are on a single electrode pad.

Abstract: Subject matter includes a method comprising: applying a first electrical signal to a subject; identifying a proposal to change the first electrical signal to a proposed second electrical signal; calculating at least one parameter of the proposed second electrical signal; and determining whether the calculated at least one parameter violates any rules. If the at least one parameter does violate any of the rules, then the method further comprises iteratively modifying one or more features of the proposed second electrical signal to arrive at a modified second electrical signal that complies with the rules. If the at least one parameter does not violate any of the rules, then the method further comprises applying the proposed second electrical signal to the subject.

Abstract: Subject matter includes a method comprising: applying a first electrical signal to particular locations of a subject via at least one electrode pair; applying a second electrical signal to the particular locations of the subject via the at least one electrode pair, wherein the second electrical signal is applied alternately and repeatedly with the first electrical signal; determining a first electrical impedance based, at least in part, on the first electrical signal; determining a second electrical impedance based, at least in part, on the second electrical signal; and removing at least a portion of varying electrical characteristics of the at least one electrode pair by calculating a difference between the first electrical impedance and the second electrical impedance.

Abstract: A projection system that projects a text or subtitle box onto an image minimizes the contrast between the text box and the image. A transition region surrounding the text box minimizes visual disruption to the image onto which the text box is projected. The positions of optical elements of a text projector enable the text box to gradually fade out. The text projector has a lamp that defines an object plane and a light path modifier. The light path modifier is offset from the object plane, toward the lamp to blend the borders of the text box into the image projected by an image projector.

Abstract: An image projection system improves the brightness and/or color balance of a projected image. The system includes an auxiliary light source from which compensating light co-propagates with polychromatic light emitted by a primary light source along a primary light path. The compensating light has an emission energy content that minimizes an emission energy imbalance introduced by the primary light source. In a first preferred embodiment, the auxiliary light source is affixed at a location near the entrance end of a light tunnel such that the compensating light coincides with the primary light path before first reflection occurs. In a second preferred embodiment, the auxiliary light source is coupled to a light reflector adjacent to the primary light source and thereby allows the compensating light to propagate through the image projection system with the same efficiency as that of the light generated by the primary light source.

Abstract: Infrared radiation receivers (40, 72) of this invention include non-imaging optical concentrators (18, 70) having light exit surfaces (52, 86); a light sensor (46) having a light entrance surface that is separated from the light exit surface by a small air gap (53); and a soft, pliable, light transmissive medium (100, 110) inserted in the gap to reduce the light transmission loss across the gap. The soft, pliable medium is held in place by either a recess (116) in the concentrator or by a surrounding annular ring (104).

Abstract: The image projection system of the present invention improves either one or both of the brightness and color balance of a projected image. The system includes an auxiliary light source from which compensating light co-propagates with polychromatic light emitted by a primary light source along a primary light path. The compensating light has an emission energy content that minimizes an emission energy imbalance introduced by the primary light source. In a first preferred embodiment, the auxiliary light source is affixed at a location near the entrance end of a light tunnel such that the compensating light coincides with the primary light path before first reflection occurs. In a second preferred embodiment, the auxiliary light source is coupled to a light reflector adjacent to the primary light source and thereby allows the compensating light to propagate through the image projection system with the same efficiency as that of the light generated by the primary light source.
