  • Patent number: 11903806
    Abstract: An artificial urinary sphincter can include a cuff configured to surround a portion of a length of a urethra. An actuator is configured to selectively apply a force to the cuff to thereby apply variable amount of pressure to the urethra. A controller is configured to adjust the application of the force by the actuator to cause the cuff to apply the variable amount of pressure to the urethra. A sensor can be in communication with the controller and configured to detect pressure applied against the cuff by the urethra. The controller is configured to cause the cuff to apply a first closing pressure to the urethra. In response to a detection of a threshold pressure increase by the sensor, the controller is configured to cause the cuff to apply a second closing pressure that is greater than the first closing pressure and that prevents urine from exiting the urethra.

  • Patent number: 11083652
    Abstract: Disclosed herein is a footplate assembly for monitoring foot position in real time, as a wheelchair is driven. Optionally, the footplate assembly can use an array of force-sensing resistors and infrared distance sensors to detect the pressure and location of the foot within the immediate confines of the footplate. The footplate assembly can be provided as an overlay to an existing wheelchair footplate structure, or the footplate assembly can be integrated into or replace an existing wheelchair footplate structure.

  • Patent number: 10143391
    Abstract: Systems and methods are provided for in vivo measurement of pressure. An implantable sensor assembly includes a pressure sensor configured to provide an analog signal representing pressure and a signal conditioning component configured to convert the pressure sensor output into a digital signal. A transmitter is configured to transmit the digital signal to an external base unit. A power control unit is configured to dynamically allocate power throughout the implantable sensor assembly, such that during an active measurement interval of the implantable sensor assembly, each of the pressure sensor, the signal conditioning component, and the transmitter are powered only for a portion of the active measurement interval necessary to perform a related function.

  • Publication number: 20090036800
    Abstract: A hair densitometer measures the number of hair shafts in a fixed area and measures the diameters of the counted hair shafts. This is done for two different areas of the head and the comparison results in a quantified measure of the thinning of a persons hair on their head.

  • Publication number: 20090037280
    Abstract: A method of business uses a hair and or scalp scanner such as a hair densitometer to raise awareness of the prevalence of hair thinning. Incentives provided to hair care providers for using the hair scanner increases the likelihood that clients of the hair care provider will be exposed the hair scanner. Sales of hair regrowth products may also be discounted for clients of hair care providers.
