Abstract: This disclosure relates to an auto run mode for initiating a heating cycle of a heated bedding product. A heated bedding product can include a bedding product body comprising a heating element and a controller electrically connected to the heating element. The controller can include a processing circuit, such as a microcontroller, that is configured to operate in an auto run mode in which a heating cycle of the heating element is automatically initiated in response to alternating current power being provided to the controller.

Abstract: In general, the controller of the present invention senses the temperature of the electric blanket in which the controller is used, and controls the temperature accordingly. The temperature is sensed using both the PTC and NTC methods discussed below, and contained within the wire. The controller adjusts the power delivered to the electric blanket based on the temperature sensed as well as on a heat setting by the user of the blanket. Additionally or alternatively, the controller uses the sensed temperature information to guard against overheating, caused either by inadvertent consumer misuse or component failure.

Abstract: An allergen particle detecting apparatus has a sample area through which environmental air is directed. A light beam is directed through the air sample so that portions of the beam will be scattered if any particles are present in the path of the beam. A beam blocking device on the opposite side of the air sample is arranged to block all light except light scattered in a predetermined angular range corresponding to a predetermined allergen particle size range. Light transmitted through the blocking device is detected by a light detector and an alarm output signal is produced if the detected amount of light is above a predetermined level.
