Apparatus and methods are disclosed for simultaneously tracking multiple finger and palm contacts as hands approach, touch, and slide across a proximity-sensing. compliant, and flexible multi-touch surface. The surface consists of compressible cushion, dielectric, electrode, and circuitry layers. A simple proximity transduction circuit is placed under each electrode to maximize signal-to-noise ratio and to reduce wiring complexity. Such distributed transduction circuitry is economical for large surfaces when implemented with thin-film transistor techniques. Scanning and signal offset removal on an electrode array produces low-noise proximity images. Segmentation processing of each proximity image constructs a group of electrodes corresponding to each distinguishable contact and extracts shape, position and surface proximity features for each group. Groups in successive images which correspond to the same hand contact are linked by a persistent path tracker which also detects individual contact touchdown and liftoff. Combinatorial optimization modules associate each contact's path with a particular fingertip, thumb, or palm of either hand on the basis of biomechanical constraints and contact features. Classification of intuitive hand configurations and motions enables unprecedented integration of typing, resting, pointing, scrolling, 3D manipulation, and handwriting into a versatile, ergonomic computer input device.

A combination mouth and nasal mask (40) for assisted respiration or CPAP is disclosed. The combination mask (40) has a frame (42) to the rear side of which is mounted a separate nasal cushion (44) and mouth cushion (46). Both the nasal cushion (44) and the mouth cushion (46) separately form a rolled edge seal around the patient's face in the vicinity of the nose and in the vicinity of the lips. Inlet air is communicated from within the housing (48) to the mouth chamber, circumscribed by the mouth cushion (46) by means of one or more interconnecting tubes (62). The proportion of air communicated to the mouth chamber (48) is controlled by the sizing and number of the tube(s), thus providing for free flow of air, restricted flow of air and pressure equalization, or zero flow of air. A mouth mask (10) for assisted respiration or CPAP also is disclosed.

A respiratory mask for continuous positive airway pressure treatment includes a cushion adapted to be positioned against the face of a patient.

The present invention is directed to a device that can be placed between two adjacent vertebrae, and that is used to repair an injury or defect in the anulus of the intervertebral disk. The implant is characterized by having a flexible structure anchored to the vertebral bone, the flexible structure connected with a patch held in place over the injury or defect. The flexible structure has a hollow interior space which can sustain inside it a hydrogel cushion. The hydrogel cushion acts as a shock absorber for the spine, maintains height of the intervertebral disk space, and prevents further disk herniation due to the narrowing of the intervertebral disk space.

The present invention is directed to a deployment system for an endoluminal device. The deployment system includes a confining sheath placed around a compacted endoluminal device. A deployment line is provided in the system that is an integral extension of the sheath. As the deployment line is actuated, the sheath retracts from around the compacted endoluminal device. As the sheath retracts from around the endoluminal device, material from the sheath may be converted into deployment line. Once the sheath is retracted from around the compacted endoluminal device, the endoluminal device expands in configuration and repairs vascular or cardiac structures of an implant recipient. Any remaining sheath material is removed from the implantation site along with the deployment line. The deployment system also includes an endo-prosthesis mounting member placed between the endoluminal device and an underlying catheter. The endo-prosthesis mounting member serves to cushion and retain the endoluminal device when constrained by the sheath and may assist in expansion of the endoluminal device when unconstrained by the sheath. The present invention is also directed to a deployment system having a deployment assembly that simultaneously expands an endo-prosthesis mounting member while removing a sheath from an expandable medical device.

A respiratory mark assembly for delivering breathable gas to a patient includes a frame and a cushion. The cushion has a non-face contacting portion structured to be connected to the frame, a face-contacting portion structured to engage the patient's face, and an intermediate portion that interconnects the non-face contacting portion and the face-contacting portion. The intermediate portion includes a gusset portion that applies a first component of force to the patient's face through the face-contacting portion. A spring structure is coupled with the face-contacting portion of the cushion. The spring structure applies a second component of force to the patient's face through the face-contacting portion. The first and second components of force applied by the gusset portion and spring structure, respectively, determine a contact force of the cushion applied to the patient's face through the face-contacting portion. The intermediate portion may also include an elastic cuff portion. Further, in the case of an oral mask, the sealing section may include a portion that is designed to promote a better seal in the chin region of the mask.

A nasal CPAP treatment apparatus is disclosed with a flow generator coupled to a nasal mask. The mask has a nasal cushion forming a nose-receiving cavity. The cushion has a triangularly-shaped frame of resilient material with a mask engaging portion connected by a side wall to a face engaging portion which has a nasal bridge region, a cheek region and a lip region. The cushion may have a portion of the side wall in the nasal bridge region being other than straight to provide an improved sealing in the nasal bridge region. A plurality of membranes, preferably three, of resilient material extend substantially around the triangularly-shaped frame. Some of the membranes are thicker in the lip region than in the nasal bridge region to improve fit of the cushion in use.

A cushioning element that has a number of substantially parallel elongate columns which buckle under an appropriate load. The cushioning element may be formed from a soft, easily deformable elastic or visco-elastic cushioning media. As a force is exerted against the cushioning element generally parallel to a column, the cushioning media may compress, and eventually the walls of the column may buckle. This equalizes pressure across the contact area of the object being cushioned.
