Abstract: Methods of measuring attributes of animal urine, using a test pad comprising multiple test patches and urine detection patches in a BAYER pattern is described. The pad comprises different test patches, each surrounded by urine detection patches. When a camera, electronics and software automatically detect fresh urine from a color change of a detection patch, nearby test patches are read with a color camera, after a specific time delay, and compared to color reference spots. Multiple layers and isolation zones in the test pad allow urine to enter the test and detection patches, while keeping urine puddles from spreading. Once used, detection and test patches are not used again. An array of many detection and test patches allows the test pad to be used for multiple urine samples in one vivarium cage before replacing. Embodiments use a mix of IR and white light, and IR cameras and color cameras.

Abstract: A test pad comprising multiple urine attribute patches and urine detection patches in a BAYER pattern is described. The test pad is suitable for automated urine analysis of multiple animals in a cage. Generalized detection patches may be arranged adjacent to and surrounding each individual test patch for a specific urine attribute. First, fresh urine is detected in a detection patch with a camera; a timer is started; then adjacent urine attribute patches are read. Once a test patch has been used once it is disregarded for future analysis.

Abstract: A test pad comprising multiple test patches and urine detection patches in an array is described. The test pad is suitable for automated urine analysis of multiple animals in a cage. Urine detection patches may be arranged in a BAYER pattern or as rings. Multiple layers, including a substrate, a wicking layer, a test patch layer, and optional protection layer serve to manage puddles of urine. Various isolation elements are described that keep urine puddles from spreading. Color reference spots on the pad are used for dynamic color determination of test patches. Urine detection patches start a read clock and identify which test patches are valid. Elements to hold and align the test pad are described. Methods of detection and reading are described.

Abstract: The invention describes an automated method, device and system for both husbandry and study purposes of animals by providing a heat reward for specific behavior. Embodiments include maintaining the cage temperature at a normal, comfortable temperature for the animals, such as mice, using radiant heat rather than conducted heat to provide the reward, using home cages for the animals, detecting the behavior fully automated, operating in animal darkness, and using cages that are free of electrical penetrations. Some embodiments have one animal in a cage. Some embodiments have or support multiple animals in a cage and include methods to detect automatically identify animals, locate animals in the cage and associate a behavior and reward for a specific animal. Some embodiments place all sensors and radiant heat sources outside the cage, or use infrared sources for both heating and for IR camera lighting.
