Abstract: As disclosed herein, a bidirectional ratchet for an anti-slippage knob-ratchet to adjust strap length for securing a virtual reality headset onto the head of a user is provided. In one aspect, the bidirectional ratchet may include a first pawl, configured to engage with a stationary ratchet drum in an outer housing to allow movement of a pinion in a clockwise direction. The bidirectional rachet may include a second pawl, configured to engage with the stationary ratchet drum to allow movement of the pinion in a counterclockwise direction. A knob system and a headset are also provided.

Abstract: A resource tracking system includes a resource storage device with multiple resources and a resource tracking application. The resource tracking application scans the resource storage device to identify the resources, determines a deployment date, an execution date, or both for each resource, identifies a subset of the resources that do not meet deployment date criteria, execution date criteria, or both based upon the deployment date, the execution date, or both determined for each resource, and recommends an action to delete the subset of the plurality of resources via a graphical user interface.

Abstract: The invention features a medical device that measures vital signs (e.g., blood pressure, pulse oximetry, and heart rate) from a patient using at least two optical modules. Each optical module typically features two light sources (red, infrared) and a photodetector. Both optical modules are configured to measure time-dependent signals describing the patient's flowing blood. A processor analyzes the time-dependent signals to determine the patient's vital signs. Once the vital signs are measured, a wireless transmitter in the body-worn device transmits them to an external device. Processing signals from least two optical modules compensates for motion-related artifacts and noise normally present in signals used to determine vital signs from a device featuring just a single optical module.

Abstract: The invention provides a system for measuring blood pressure from a patient that includes: 1) an optical module configured to be worn on the patient's ear and comprising at least one optical source and a photodetector; 2) a calibration source configured to make a blood pressure measurement; and, 3) a processing module configured to: i) receive a first signal from the optical module; ii) receive a second signal from the calibration source; iii) process the first and second signals to generate a calibration table; and iv) receive a third signal from the optical module and compare it to the calibration table to determine the patient's blood pressure.

Abstract: The invention provides a system for measuring blood pressure from a patient that includes: 1) an optical module featuring systems for measuring signals from the patient, serial communication, and power management; 2) an external computing device configured to attach to the optical module, supply power to the optical module, and receive information from the optical module through the system for serial communication; and 3) an algorithm, operating on the external computing device, that processes information received through the system for serial communication to determine the patient's blood pressure.

Abstract: The present invention provides a system for monitoring blood pressure that preferably includes: 1) a blood-pressure monitor featuring a measuring component that generates blood-pressure information and a first short-range wireless component configured to wirelessly transmit the blood-pressure information; 2) a mobile device featuring a chipset that includes i) an embedded second short-range wireless component configured to receive the blood-pressure information; and ii) a long-range wireless component configured to transmit the blood-pressure information over a wireless network; and 3) a computer system configured to receive and display the blood-pressure information.
