Abstract: This relates to methods for measuring irregularities in a signal and corresponding devices. The devices can include a PPG sensor unit configured to detect multiple occurrences of a given event in the measured signal(s) over a sampling interval. In some instances, the device can register the occurrences of the events. In some examples, the device can include one or more motion sensors configured to detect whether the device is in a low-motion state. The device may delay initiating measurements when the device is not in a low-motion state to enhance measurement accuracy. Examples of the disclosure further include resetting the sample procedure based on one or more factors such as the number of non-qualifying measurements. In some examples, the device can be configured to perform both primary and secondary measurements, where the primary measurements can include readings using a set of operating conditions different from the secondary measurements.

Abstract: An insect repelling device includes abase and a cap. The base supports a fluid reservoir containing a vaporizable insect repelling fluid. The cap has an exhaust port that permits a vapor of the insect repelling fluid to be emitted. The cap permits condensation of the insect repelling fluid vapors of the insect repelling fluid to flow toward the exhaust port.

Abstract: An evaporator is provided, for use with a wicked reservoir containing a volatile liquid. The reservoir has a plurality of guide members disposed symmetrically around the wick and extending beyond the height of the wick. The evaporator features a base containing a battery, and a removable cover containing a heater. Attachment of the cover to the base is necessary to establish an electrical connection between the battery and the heater. The guide members fit into recesses in the cover only when the heater and wick are properly aligned, and the heater cannot make electrical connection with the battery unless the guide members and wick are properly aligned with the recesses and heater, respectively.

Abstract: A battery powered insect repellent device capable of the battery being separated from the volatile dispenser element and further including wireless communication facilities between a smartphone and the repellent device enabling electronic monitoring of the status of the various elements in the device as well as displaying the same to the user.

Abstract: Mats of different sizes formed of single mats having different sizes or a multilayer mat which are provided for area insect repellent devices which contain a heat plate to heat the mat structures carried thereabove, thereby providing different operating characteristics of the repellent device.

Abstract: A garment having added exterior pockets in which low temperature volatizable insect repellent mats may be carried which disperse the volatizable chemical at ambient temperature or in which an additional exothermic mat is provided to assist in the dispersion of the chemical.

Abstract: A unit for dispensing repellant having a heating element powered by hydrocarbon combustion. A tank connection assembly within the unit attaches a fuel cartridge and a valve activator controls fuel flowing from the cartridge. A lever that is communication with the fuel activator is independently controllable by a user to initiate and terminate flow of fuel and also is controllable by the unit's cover to terminate fuel flow.

Abstract: A medical device such as a retractor or isolation bag including an inflatable member which expands from a collapsed configuration to an expanded configuration when pressurized gas or liquid is supplied thereto. The member can include a plurality of fluid channels, ribs and pre-shaped wire members. The device is inserted into a body cavity through a tube. The device can also be actuated by a honeycomb reinforcing structure with or without the use of pressurized fluid. The device can be manufactured by forming one or more air conduits in a member of expandable material or by enclosing a honeycomb reinforcing structure in a polymer material.
