Abstract: A portable blood pressure measurement device with a removeable/replaceable cuff is disclosed. The device can be capable of wirelessly interacting with a secondary device, such as a cell phone, to measure blood pressure of a patient and configurable to fold into a low profile storage configuration. The removable cuff is sized and configured for wrapping around the limb of a subject the cuff further having an inflatable bladder formed integrally therein; one or more tubes positioned within the cuff in communication with the inflatable bladder; an exhaust valve; a housing connected to the cuff wherein the housing houses one or more of a controller, a memory, a pump, a power supply, and a motor. A transmitter can be provided for wirelessly transmitting blood pressure data to a second device. Operation of the device is furthermore changeable in response to a detected cuff size.

Abstract: Described are apparatuses (e.g., devices, systems, software), and methods for monitoring the cardiac health of a patient which incorporates secondary information. The apparatus may be a heart rate monitor, a blood pressure monitor, an ECG or other biometric device in communication with an electronic device having communication ability. The devices detect a cardiac or other biometric measurement and correlate the detected information with secondary information, such as GPS data, to produce a contextualized measurement.

Abstract: Devices and methods are described to enable devices to be paired in a convenient and secure way based on proximity with the use of a single radio transmission protocol. Using devices configurable to perform the processes described, users are able to pair Bluetooth enabled devices or other radio communication protocols simply by putting the devices briefly in contact, or within close proximity, usually few centimeters. When the two devices touch or are in close proximity, the encryption key is shared across the two devices without further interaction required by the user. The encryption key is not made visible, so one potential source of security breach is eliminated. After first setup, proximity is not required and the device can communicate securely based on the previously exchanged security tokens (and encryption keys) without the requirement of proximity.

Abstract: Device segmentation systems and methods enable devices to be manufactured and placed into the stream of commerce without customization for a particular retailer. The customization occurs at a later point in time when the device is activated after sale. This allows devices to be transferred among retailers without the additional expense of re-customizing the device.
