摘要:
A negative pressure wound therapy apparatus can include a wound dressing, a fluid collection container, a vacuum pump comprising a pump motor, and tubing. Additionally, the apparatus can include a pressure sensor that measures a pressure in the tubing. One or more tubes can channel a fluid between the wound dressing, the fluid collection canister, and the pump. In addition, first and second control circuits can be provided for controlling the pump motor without using a processor. The first control circuit can generate a difference signal between a desired pressure input and a pressure sensor input, and can further generate a motor control signal responsive to the difference signal. Moreover, a second control circuit can provide an override signal based at least in part on the difference signal and at least one reference signal. The override signal beneficially overrides the motor control signal to prevent the pump motor from stalling.

摘要:
A system and method for analyzing tissue healing may include capturing an image including a tissue site. A clinician may be enabled to define multiple regions of the image of the tissue site, where at least two of the regions of the image define tissue types at different stages of tissue healing. An area may be calculated of each of the at least two regions of the image defining tissue type at different stages of tissue healing. The calculated areas may be displayed to a clinician. In one embodiment, an image color adjustment may be determined by adjusting the image of the reference color marker to the predetermined color. The image of the tissue site may be normalized by applying the image color adjustment to generate a normalized image.
摘要:
A therapeutic device for providing intermittent negative pressure wound healing includes a fluid mover, a compressible therapeutic member operably connected to the fluid mover and actuated thereby, the compressible therapeutic member operably disposably used on a patient in a manner to deliver therapy to the patient as function of actuation of the fluid mover and a controller for controlling application of a negative pressure to the compressible therapeutic member about a wound in a manner to compress the compressible therapeutic member using negative pressure to subject the wound and the compressible therapeutic member to a first predetermined pressure to maintain a seal between the compressible therapeutic member and the wound and decompressing the compressible therapeutic member to a second sub-atmospheric pressure above the first predetermined pressure sufficient to maintain the compressible therapeutic member in generally sealed contact with the wound.
摘要:
An articulated and animated toy capable of recognizing human users and selected inanimate objects and interacting therewith which includes a computer-based device having stored thereon encoded first human or human-like facial images, a video camera and video digitizer for acquiring data representative of a second human or human-like facial image, and software resident within said computer-based device for facial recognition, which includes Principal Component Analysis, Neural Networks, or another equivalent algorithm for comparing said first human or human-like facial images with said second human or human-like facial image and producing an output signal therefrom for use in identifying said human users. The apparatus can further include software for recognizing speech, generating speech and controlling animation of the articulated toy. In addition, said computer-based device is capable of learning and storing information pertaining to each of said human users such as name, age, sex, favorite color, etc., and to interact with each of said human users on an individual basis, providing entertainment tailored specifically to each of said human users.
摘要:
An access control apparatus and method. Enrollment is conducted at a centralized server and enrollment data, such as identification data is downloaded to plural local access units at respective entrances to a restricted area. The local access units then collect data of a person upon an attempted entry in to the area and compare the data with downloaded enrollment data to determine if the person is authorized for access. If the person is authorized, an access control device is operated to open a door, gate, or the like of the entrance. The enrollment data can be biometric data and the same type or different type of biometric data can be collected at the local access units. If a different type of data is collected at the local access units and is correlated to data stored on the local access unit, data of the same type as the downloaded data is collected and compared to the downloaded data for access control. The enrollment data can be non environmentally affected data, such as fingerprint parameter data and the different type of data can be environmentally affected data, such as facial parameter data.
摘要:
An identification and verification system which includes a card, or the like, having stored thereon human facial image projection characters, means for retrieving the human facial image projection characters and manipulating the same to produce an output signal indicative of a human facial feature for use in identification and verification. The retrieving means includes universal face space (UFS) memory indicative of facial features for a non-homogeneous population wherein the output signal is generated by projecting the projection characters into the UFS memory.
