  • Publication number: 20120130255
    Abstract: Medical device or instrument for diagnosing pressure ulcers using optical reflectance spectroscopy. The device may comprise a tip and a controller. The tip is pressed against the skin of the patient and collects the optical reflectance data. The controller processes the data to determine whether there exists a pressure ulcer and, if there is one, its depth. The tip may also include a pressure sensor for sensing the pressure at which the tip is applied to the patient's skin.

  • Publication number: 20100234193
    Abstract: An exercise assembly for performing multiple exercises includes a pivotable bar assembly and a dip bar assembly. The pivotable bar assembly extends through a frame and has a central bar connected between first ends of a pair of swings arms, with second ends of the swing arms pivotably connected to facing surfaces of the frame. The dip bar assembly extends across a front side of the frame and includes a main tube with a pair of handles extending outward from the main tube and resting on the center bar of the bar assembly.

  • Publication number: 20100113225
    Abstract: A counting device for counting repetitions and timing a push-up exercise includes a device body and a counter assembly having a display and a plurality of actuation buttons thereon. The counter assembly fits within a deformable foam ring that forms the top of the device. During exercise, a user depresses the foam ring downward with their chest a given distance so as to trigger at least one sensor in the counter assembly to register a repetition count on the display, along with an elapsed time of the exercise. The counter assembly can be fixed within the device, or a display unit thereof may be removable so that the device and display unit are configured for wireless communication.

  • Publication number: 20090186750
    Abstract: A push-up exercise unit and device is described which may enable a user to move with his or her body's natural rotation to engage additional muscle groups with reduced stress on joints. The device includes a pair of rotatable devices, one for each hand. Each rotatable device includes a handle assembly, a rotatable handle support structure, a fixed base support, and a bearing assembly operatively attached within the handle support structure to permit rotation of the handle assembly and handle support structure. The handle assembly is removable from a top surface of the handle support structure, to be inserted into another surface of the handle support structure to configure the unit for stowage.

  • Publication number: 20090186751
    Abstract: A push-up exercise unit and device is described which may enable a user to move with his or her body's natural rotation to engage additional muscle groups with reduced stress on joints. The device includes a single molded housing with a circular lower base and an integral downwardly extending facing formed around a circumference of the lower base. The housing includes a pair of facing columns formed into part of the base of the housing and forming part of the facing at opposing sides thereof to receive an end of a handle there between. The device includes a fixed base support operatively attached to the housing, and a bearing assembly operatively attached within the housing to permit rotation of the contiguous handle and housing by a user with the fixed base support resting on a planar surface.

  • Patent number: 7468025
    Abstract: A push-up exercise unit and device is described which may enable a user to move with his/her body's natural rotation to engage additional muscle groups with reduced stress on joints. The device can include a handle support structure having a pair of columns between a lower base and a separate end cap such that the handle intersects a corresponding end cap and upper portion of a corresponding column of the handle support structure. The device includes a fixed base support attached to the handle support structure, and a bearing assembly to permit rotation of the contiguous handle, end caps and handle support structure by a user with the base support resting on a planar surface. In another example, the handle assembly is detachable from a first surface on the handle support structure and inserted into a second surface to facilitate stowage for travel.
