The invention comprises devices for noninvasively monitoring physiological characteristics of a patient's blood. Generally, probes having radiation emitters and detectors are used to determine absorbance of blood within the patient's tissue to determine various blood parameters. The device also has either a position sensor for determining the position of the probe with respect to the patient's heart or a movement generator for altering the position of the probe with respect to the patient's heart. The invention also comprises methods for noninvasively monitoring the physiological characteristics. In one embodiemnt, induced positional changes create differential hydrostatic pressures to facilitate measurement of blood parameters by absorbance. In a second embodiment, delays in pulse arrival times in coupled organs or members on opposite sides of the body are measured to determine cardiac output. The two methods are such that they can advantageously be used together.

A collapsible hunting blind includes a blind awning and a collapsible frame. The blind awning includes two sidewalls, a front wall, a rear wall, and a top wall. The collapsible frame includes a retention frame and two tensional frames.

A collapsible hunting blind includes a blind awning and a collapsible frame to fold the blind awning between a folded position and a setup position. The blind awning comprises two sidewalls, a front wall, a rear wall, and a top wall. The collapsible frame includes a retention frame and two tensional loops. The retention frame is detachably coupling between the sidewalls to retain a distance therebetween, wherein when the retention frame is released from the sidewalls, the sidewalls are adapted to overlap with each other. The two tensional loops are provided at the sidewalls respectively for providing a tensional force thereat at the setup position to stretch out the sidewalls in a tensional manner, wherein when each of the tensional loops is twist-folded to reduce the tensional force at the respective sidewall, the overlapped sidewalls are adapted to twist-fold into a compact structure at the folded position.

A finishing wheel holding mechanism for a gear finishing apparatus using a finishing wheel having internal teeth, which permits simple and quick fitting or replacement of a finishing wheel is provided. The finishing wheel holding mechanism comprises a head frame 21 having at the center an opening portion for holding a finishing wheel, and an annular finishing wheel holder portion 22 for fitting finishing wheels A1 (A2), supported rotatablly within the opening portion of the head frame 21; and the finishing wheel holder comprises a support gear 50 having an open end portion 53 for finishing wheel insertion and an accepting portion 54 for fixing the finishing wheel, an annular shifting body 55 within the open end portion 53, a projection 57 contacting the finishing wheel to serve as a stopper, a pressing collar 58 inserted into the shifting body 55 to fix the finishing wheel by sliding the shifting body toward the finishing wheel, and an actuator 60 for driving the shifting body 55 toward the accepting portion.

An aircraft wing slat for mounting to a leading portion of an aircraft wing includes a main body section and a forward section, wherein the forward section is demountable from or releasably secured to the main body section. The forward section may have a nose skin with an electrically powered heater. The electrically powered heater may be integral with the nose skin and may be microporous such that it is integrated into surrounding dielectric to contribute to the mechanical strength of the nose skin. A demountable forward section of an aircraft wing slat, a main body section of an aircraft wing slat arranged to receive a demountable forward section, an aircraft wing and an aircraft wing slat with a nose skin with an electrically powered heater are also disclosed.

An adjustable easel having a canvas holder and a base is provided. The canvas holder is attached to the base in a way that the canvas holder can swivel with respect to the base and the canvas holder can be tilted with respect to the base. A connecting device includes a canvas holder bracket that is fixed to the canvas holder, a first shaft on which the canvas holder bracket is rotatably attached so that the canvas holder can be tilted, a second shaft on which the first shaft is fixed, and a base bracket that is fixed to the base. The base bracket is rotatably attached to the second shaft so that the canvas holder can swivel. The canvas holder includes a gripping device that grips a canvas and is adjustable to accommodate different sizes of the canvas.

A static hinge disabler is provided for preventing the operation of a door hinge. The static hinge disabler includes a first sidewall, a second sidewall, a channel, and a cap. The first sidewall is substantially parallel to the second sidewall. The channel is disposed between the first sidewall and the second sidewall and configured to receive at least a portion of the door hinge therein. The first sidewall and the second sidewall are statically connected such that the channel does not change shape. The first sidewall and the second sidewall therefore prevent the door hinge from operating while the door hinge is disposed within the channel.
