The invention provides a system and method for measuring vital signs (e.g. SYS, DIA, SpO2, heart rate, and respiratory rate) and motion (e.g. activity level, posture, degree of motion, and arm height) from a patient. The system features: (i) first and second sensors configured to independently generate time-dependent waveforms indicative of one or more contractile properties of the patient's heart; and (ii) at least three motion-detecting sensors positioned on the forearm, upper arm, and a body location other than the forearm or upper arm of the patient. Each motion-detecting sensor generates at least one time-dependent motion waveform indicative of motion of the location on the patient's body to which it is affixed. A processing component, typically worn on the patient's body and featuring a microprocessor, receives the time-dependent waveforms generated by the different sensors and processes them to determine: (i) a pulse transit time calculated using a time difference between features in two separate time-dependent waveforms, (ii) a blood pressure value calculated from the time difference, and (iii) a motion parameter calculated from at least one motion waveform.

Accelerometer-based orientation and / or movement detection for controlling wearable devices, such as wrist-worn audio recorders and wristwatches. A wrist-worn audio recorder can use an accelerometer to detect the orientation and / or movement of a user's wrist and subsequently activate a corresponding audio-recorder function, for instance recording or playback. A wearable device with a vibration mechanism can use this method to remind a user of an undesirable movement such as restless leg movement. Likewise, a talking wristwatch can use this method to activate audio reporting of time when a user moves or orients his or her wrist in close proximity to his or her ear. In such applications, and many others, accelerometer-based control of the wearable device offers significant advantages over conventional means of control, particularly in terms of ease of use and durability.

The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.

A lighted helmet having a protective shell having: an outside surface, a plurality of lamps which emit light from the outside surface; a power supply, typically a battery; and a motion detecting switch in communication with the power supply and the plurality of lamps. When the helmet is worn by a user, even small movements of the head produce forces, which in turn, trigger the motion detecting switch. Upon triggering of the motion detecting switch, the lamps are illuminated for a predetermined period of time. Upon expiration of the time period, subsequent motion will retrigger the switch, once again activating the lamps. The process continues until the helmet is placed in a stationary position, at which time the lamps are extinguished upon expiration of the then active time period.
