Abstract: A jacket 101 has a detector, such as a gas detector, for detecting an environmental hazard. The jacket has a first warning device for issuing a first warning in response to detecting the environmental hazard. Furthermore, the jacket is provided with a transmission device for transmitting a warning signal to similar jackets worn by operatives within the environment. Each jacket includes a second warning device for issuing a second warning in response to receiving a warning signal from any other jackets or clothing.

Abstract: This disclosure provides systems and methods for delivering a neural stimulation pulse. A neural implant device can include an energy harvesting circuit configured to receive an input signal and generate an electrical signal based on the received input signal. A diode rectifier in series with the energy harvesting circuit can rectify the electrical signal.

Abstract: A MEMS gyroscope is provided. A substrate can be formed with a substantially planar surface, a substantially hemispherical cavity extending into the surface, an actuation electrode, and a plurality of sensing electrodes. A resonator formed from a substantially hemispherical shell can be suspended within the cavity by a stem coupling the center of the bottom of the cavity to the center of the bottom of the shell. An electronic processor can be configured to cause a voltage to be applied to the actuation electrode, receive signals from the sensing electrodes, and process the received signals to determine rotation of the MEMS gyroscope.

Abstract: Methods for preserving catalytic activity of a PSA polymer membrane in a humid environment by immobilizing in the membrane an organic acid having a pKa greater than the pKa of the PSA polymer membrane; optical sensors based on the PSA membranes further including an immobilized organic reagent capable of reacting with a target compound in a humid environment to produce a detectable color shifted product; and non-invasive methods for estimating blood glucose concentration by utilizing an optical sensor to detect concentration of acetone in exhaled human breath and correlating it to blood glucose concentration.

Abstract: A control module (105) is supported within an item of clothing. The control module is located within a pocket (503). A visual indicator (1201) is pressed on the jacket at a positon in front of the activation button on the control module. The activation button has a surface area that covers at least 40% of a surface area of the control module. In this way, it is possible for the control module to move within the pocket while still facilitating activation and deactivation upon pressing the visual indicator.

Abstract: A method of intranasal treatment of nasal symptoms administered to a human in need of the treatment includes administering intranasally from an internasal spray container a composition having a therapeutically effective amount of capsicum extract to a human in need thereof; and effecting relief from at least one symptom. The symptom relieved includes at least one of nasal congestion, sinus pressure, headache, sinus pain or a combination thereof. The first relief of sinus pain, sinus pressure, or nasal decongestion in the human occurs within about 30 minutes of administration.

Abstract: An item of clothing in the form of a jacket provides enhanced visibility for a cyclist. A right detection device is configured to identify a raising of a right arm and a right indictor light (103) is configured to indicate in response to the raising of the right arm.
