  • Patent number: 11173073
    Abstract: Methods and apparatus are disclosed for monitoring incontinence events using inexpensive sensors coupled to an incontinence brief worn by a patient. In some examples of the disclosed technology, a radio frequency identification (RFID) tag is queried to return a sensor value indicating a level of moisture in an incontinence brief. A mobile device carried by a patient caregiver analyzes the sensor value and provides a display indicating a course of action to take, for example, whether to change the patient's incontinence brief.

  • Publication number: 20180242751
    Abstract: The invention is directed to modules for installation in beds to adjustably support targeted body zones of a user. Modularization renders actively controlled bed technology available to a broad range of beds on the market including upgrading many users' existing beds. Bed actuation modules include one or more lift systems connected to a mechanical support which has bed mounting devices for enabling installation of the module in a broad range of bed frames. An adjustable height platform of each lift system can be raised or lowered without necessarily changing the angle of inclination thereof. Lift systems for variable support of two zones may be actuated by single actuator in a way that provides contra-acting movement of the respective mattress support surfaces. Optionally, inclusion of a sensing and inference system enables automatic control of a bed actuation module according to the inferred orientation of a user's body.

  • Patent number: 7523204
    Abstract: A process for quiescing a master (master) and a plurality of subordinate computer systems (subordinates) in a cluster. An original or a pending state may be entered that is a quiesce or an online state. The master instructs the subordinates the quiesce or online state be made the pending state. The subordinates prepare to change accordingly, determine whether successful, and vote to commit or abort. Based on whether all voted to commit, the master instructs the subordinates to either commit or abort. If to commit and the pending state is the quiesce state, an operation is performed in the subordinates. If to commit and the pending state is the online state, the subordinates prepare to resume the original state. The subordinates change from the original to the pending state. Otherwise, if to abort, the subordinates prepare to remain in the original state and reset the pending to the original state.
