  • Publication number: 20240115440
    Abstract: A patient handling apparatus includes a patient support surface, a base, and a hydraulic circuit. The hydraulic circuit includes a pump, a fluid reservoir, and a hydraulic cylinder operable to selectively raise or lower the patient support surface or the base. The hydraulic circuit controls flow of fluid between the cylinder and the fluid reservoir to thereby control the movement of the base or patient support surface. In addition, the hydraulic circuit may include a manual bypass circuit configured to bypass the pump in response to a manual input, which allows manual extension or retraction of the cylinder, for example, when the pump is not operational. The hydraulic circuit may also include a pump bypass circuit configured to bypass the pump to allow fluid to discharge from the cap end to the fluid reservoir for faster evacuation of fluid from the cylinder, thereby increasing retraction speed of the rod.

  • Patent number: 9672406
    Abstract: This disclosure is of a biometric authentication system and method. The system includes a mobile device having a camera and a screen, and a database. The system is programmed to superimpose on the screen an overlay of a finger over a real-time image seen by the camera, capture an image of a fingerprint of a user with the camera, compare the captured image with an authenticated fingerprint image that is stored in the database, and return a positive result if the compared images match.
