Abstract: Embodiments of putter-type golf club head comprising a striking surface capable of achieving consistent ball speeds across the striking surface to account for various ball impact locations are described herein. The striking surface has at least two materials that differ in concentration away from the geometric center of the striking surface to provide this consistency. Consistent (or uniform) ball speed is achieved throughout the striking surface as the portion of the golf ball that contacts the striking surface interacts with at least two materials having a differing material characteristic.

Abstract: A folding chair having adjustable, telescoping rear legs for use on level ground and sloping terrain. The chair is continuously adjustable by a user while in a seated position, each of the telescoping rear legs housing a biasing means to mechanically assist the user in their adjustment. Easily-deployable clamps are provided to enable a user to adjust the inclination of the seating arrangement with a single hand.

Abstract: A folding chair having adjustable rear legs for use on flat, even ground and in addition, on sloping terrain from about zero degrees to twenty degrees and being continuously adjustable over this range by a user in a seated position.

Abstract: A pacifier pulse oximeter sensor includes pulse oximeter sensor elements located within the nipple of a pacifier. The pulse oximeter sensor elements may be completely within the nipple material, embedded within the nipple material, nested within the nipple material, or adjacent to the nipple material while not being exposed to the outside environment. The pulse oximeter sensor elements include a light source and a light detector. The pulse oximeter sensor elements communicate with an oximeter through wiring, an electrical connector, and/or wirelessly. An alternative embodiment adds oximeter processing capabilities to the pacifier pulse oximeter sensor.

Abstract: Sturdy and easily adjustable lawn furniture provides for use on sloped surfaces ranging from zero to thirty degrees. Provisions are made so that adjustment of the furniture made be effected while in use. Additional features include a drink holder and a holder for printed materials.

Abstract: A device for taking reflectance oximeter readings within the nasal cavity and oral cavity and down through the posterior pharynx. The device preferably includes a reflectance pulse oximeter sensor that preferably is resistant to bodily fluids to contact one of these capillary beds for the taking of readings and then for sending of these readings to a spectrophotometer or like device.

Abstract: A combined nasopharyngeal airway and pulse oximeter sensor capable of monitoring the posterior pharynx, posterior soft palate or nasal mucosa is disclosed. The nasopharyngeal airway includes a thickened wall section over approximately one-third of its circumference. Pulse oximeter sensor elements may be embedded in the airway. The pulse oximeter sensor elements may include a light source, which preferably emits light at wavelengths around 660 nm (red) and around 940 nm (near infrared), and a light detector. The pulse oximeter sensor elements may be connected to a pulse oximeter monitor (spectrophotometer) or other external device for analysis.

Abstract: A combined oropharyngeal airway/bite block is disclosed having pulse oximeter sensor elements capable of monitoring the posterior pharynx, the soft palate, the hard palate, and the buccal surface. The oropharyngeal airway portion has a thickened wall to house the pulse oximeter sensor elements and provide sufficient material to form grooves in the distal end. The grooves are utilized when the invention is turned on its side to act as a bite block with the grooves engaging the teeth of the patient. The pulse oximeter sensor elements include a light source, which emits light at wavelengths of about 660 nm and about 940 nm, and a light detector. The pulse oximeter sensor elements are in communication with a spectrophotometer for analysis.

Abstract: A sequence camera for recording a series of images on a strip of photographic film employing a rotating shutter and an intermittant film advance mechanism. A motor drives the shutter and the film advance mechanism. The film advance mechanism utilizes a beater wheel with two protruding pins spaced unequally about the circumference and a spoke wheel with a plurality of spokes. As the motor drives the beater wheel, the pins intermittently engage the spokes of the spoke wheel, which, in turn, intermittently advances the film. The film is exposed by the shutter during the stationary period between advancements.
