Abstract: An article is provided that permits a user to stay comfortable and warm in nearly any situation involving a chair or seat. The article includes a blanket portion that is connected to an elastic or inelastic fabric cover/pocket, which can be sleeved over the back of a chair. The cover keeps the blanket securely held in place on the chair. The design permits users to quickly move the blanket from one chair to the next, quickly get in and out of the chair, and quickly secure the blanket in the configuration that achieves the desired level of comfort and warmth. The design purposefully allows the user to cover the front and the back of their bodies. One or more detachable ‘seat belts’ connect the sides of the blanket, one to one another, creating an adjustable, custom, snug fit. Because the legs and feet are secure inside the blanket, the blanket is kept away from office chair wheels when rolling an office chair, thus the blanket does not get stuck in or under the wheels.

Abstract: Valve assemblies include a valve body having a fluid passage through the valve body and a valve member disposed in a chamber of the valve body. The valve assembly further includes a first seat and a second seat, where both seats are configured to contact and provide a seal between the valve body and the valve member to at least partially inhibit fluid flow through the fluid passage. Methods of providing a seal in a valve include forcing a primary seat into a seat portion of a valve body to provide a seal between a valve member and the valve body with the primary seat and deflecting at least one arm of a secondary seat to provide another seal between the valve member and the valve body with the secondary seat.

Abstract: A device for use in physical therapy is provided. The device includes an axis, and a plurality of rollers which are rotatably mounted on the axis. Each roller is equipped with a shaft through which the axis extends. The surface of the shaft is equipped with a plurality of spaced apart protrusions, and an adjustable locking feature disposed on the axis that rotatably and releasably engages the grooves formed by the spaces between the protrusions such that the distance between the rollers may be adjustably fixed to any of a plurality of predetermined values.

Abstract: The present invention provides a method for approximating the flow rate of hydraulic fluid in an automatic transmission. The method includes estimating a flow rate value for each of a plurality of temperatures. Thereafter, the current transmission temperature is measured. The flow rate corresponding to the current transmission temperature is then learned in the following manner. The process of learning the flow rate initially includes identifying the presence of a predefined shift aberration. If the predefined shift aberration was not identified, the flow rate estimation corresponding to the current transmission temperature is iteratively adjusted. If the predefined shift aberration was identified, the flow rate estimation corresponding to the current transmission temperature is reversed by one iterative step thereby providing the learned flow rate value for the current transmission temperature.

Abstract: A device measures the operating angle of a universal joint in a drive train system without any physical contact with the components of the drive train system. The drive train system can include first and second shafts that are connected together by the universal joint. The device includes a first sensor for generating a first signal that is representative of the angular orientation of the first shaft relative to the horizontal and a second sensor for generating a second signal that is representative of the angular orientation of the second shaft relative to the horizontal. Each of the first and second sensors can include a pair of non-contact sensors, such as a pair of laser distance sensors, that are mounted on a base. A controller is responsive to the first and second signals for determining the operating angle of the universal joint.
