Abstract: A test kit detects the presence of a target analyte in a fluid sample. In particular, the test kit includes reagents capable of detecting the target analyte of interest in breast milk. More particularly, the test kit is capable of detecting the presence of alcohol, caffeine, nicotine, drugs of abuse, therapeutic drugs, triglycerides, lactose, capsaicin, and gluten, for example, in breast milk.

Abstract: The sonar device includes a sonar transducer, a noise filter, a microprocessor and an output device. The system warns the user when a hazardous objects is detected or when signals from companions decrease. The portable sonar device can be built into various watersport devices including scuba diving equipment, surfboards and windsurfboards.

Abstract: A communication system includes a front-end multi-throw switch, a back-end multi-throw switch, multiple filters and a switch controller. The front-end multi-throw switch includes front-end throws and a front-end pole. The front-end pole is coupled to a receive channel or a transmit channel. The front-end pole is switchably coupled to one of the front-end throws. The back-end multi-throw switch includes back-end throws and a back-end pole. Each of the back-end throws is associated with a corresponding one of the front-end throws. The back-end pole is coupled to the receive channel or the transmit channel. The back-end pole is switchably coupled to one of the back-end throws. The one of the back-end throws corresponds to the one of the front-end throws. The filters are interposed between the front-end multi-throw switch and the back-end multi-throw switch. Each of the filters has a first port coupled to one of the front-end throws and a second port coupled to one of the back-end throws.
