Abstract: Systems and methods are disclosed which provide for a “factory-calibrated” sensor. In doing so, the systems and methods include predictive prospective modeling of sensor behavior, and also include predictive modeling of physiology. With these two correction factors, a consistent determination of sensitivity can be achieved, thus achieving factory calibration.

Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Abstract: An internally supported cushion for a seating unit is provided. The internally supported cushion includes an internal structure that provides rigidity when used adjacent a back upright or a side upright of a seating unit. The internal structure generally includes a rigid core element that is sandwiched between foam layers. The rigid core element is approximately upright and extends in the lengthwise and widthwise directions of the internally supported cushion. A batting layer is positioned immediately beneath an upholstery covering to prevent the covering from contacting the internal foam layers, which encapsulate the rigid core element.

Abstract: A weight-responsive chair is provided which has a weight-activated mechanism that resists rearward tilting of a chair back upright while also effecting lifting of a rear portion of the seat to counteract the rearward tilt forces. The weight-activated mechanism includes a spring package connected between the chair frame and back upright which provides for ready mounting of same to the chair frame. Further, the rear seat portion is connected in lifting engagement with the upright but also includes independent suspension for the center of the rear seat portion to allow for independent movement and flexing thereof to improve comfort for the chair occupant.

Abstract: A chair having a back assembly which includes a common back frame, multiple interchangeable crossbars, and a resiliently flexible cover. The cover includes an open interior or pocket which is adapted to receive the crossbar therein and prevent dislodgement of the crossbar. During assembly, the crossbar is first inserted within the open interior of the cover and then fitted into engagement with the back frame wherein the crossbar is held in place by stretching the cover and then engaging the lower edge of the cover with the back frame.

Abstract: A height adjustment mechanism in a chair operates automatically by raising and lowering a chair component such as a chair back. The height adjustment mechanism is provided on a chair back or other chair support and includes a gear which engages a rack member that is vertically movable relative thereto in response to movement of the chair back. A locking member is provided which engages the gear to prevent downward movement of the chair back while still permitting upward movement of the chair back. A disengagement member also is provided to separate the gear and the locking member and maintain the gear in a disengaged position that permits lowering of the chair back.

Abstract: An upright water extraction cleaning machine having an assembly of tanks efficiently stored on and interconnected to the machine is shown. The tank assembly has at least two tanks nested with one another and having one-way valve mechanisms on the bottom thereof. The two tanks are slidably mounted to one another and the tank assembly is slidably mounted and operatively connected to the machine. With this structure, the user can quickly and easily remove and refill the tanks and continue operation of the machine with a minimum amount of interruption and delay.

Abstract: A water extraction cleaning machine has a suction nozzle assembly with two suction nozzle openings incorporated. The suction nozzle openings are preferably positioned one on each side of the cleaning solution spray nozzles so that the cleaning machine can be used for simultaneous application and removal of cleaning fluid regardless of whether the user is pushing or pulling the cleaning machine. In another aspect, a plate member is slidably mounted to the bottom of the suction nozzle assembly. The plate member has a pair of suction nozzle openings which are spaced to seal one of the two suction nozzles of the suction nozzle assembly depending upon the direction of travel of the suction nozzle assembly.

Abstract: The post arrangement has a cross section which is substantially greater than the panel thickness, and is adapted to partially telescope over the end of one or more panels. The post arrangement defines therein an inwardly opening slot which is vertically elongate so as to permit an end edge portion of the panel to project therein. The slot can accommodate the end edge of a single panel or can be of sufficient angular extent to accommodate the end edge portions of two panels oriented in generally perpendicular relationship to one another.
