A scavenger grille may be coupled in the mouth opening. The muzzle and grille are formed of material that is at least partially transparent.

Abstract: A releasable coupling device for use with a pet includes a body, having an aperture, and a sleeve that is positioned at least partially around, and moveable relative to, at least a portion of the body. The sleeve is moveable between an open position in which at least a portion of the aperture is at least partially unoccluded so as to permit coupling of the device to an attachment receivable within the aperture, and a closed position in which at least a portion of the aperture is at least partially occluded so as to resist decoupling of the device by removal of an attachment from the aperture. The device defines a track configured to guide an attachment receivable within the aperture along a movement path.

Abstract: A pulse sensor is capable of measuring a pulse rate of a wearer at a peripheral artery. In an embodiment, the pulse sensor includes a magnet supported to move responsive to an arterial pulse and a magnetometer configured to detect changes in a magnetic field produced by the magnet. The magnet may include a plurality of ferromagnetic particles disposed in or on a flexible substrate configured to be held adjacent to human skin subject to arterial palpation and a magnetic sensor configured to sense movement of the ferromagnetic particles. A system and method may measure hydration includes using a pulse sensor to measure pulse rate and modulation. The wearer is prompted when the pulse rate and pulse modulation indicate a response to dehydration of the wearer.

Abstract: The invention includes pet toys made of multiple layers of material, and more particularly, to pet toys with an exterior constructed with multiple layers assembled in an offset manner resembling protective armor. The body or core of the pet toy is made of a plurality of armor plates or pieces that overlap one another in a desired configuration to present the desired armor. A central core or spine element may serve as a threading element to secure armor plates to one another. One embodiment includes armor plates that are stacked upon one another and are therefore disposed along a longitudinal axis. Another embodiment includes armor plates that are placed laterally or side-by-side with one another to form a row, and a plurality of rows are then connected to one another. The invention also includes a method for entertaining an animal with the pet toy having the multiple layers of material.

Abstract: An automated circuit test system includes a magnetic sensor array configured to measure, at a plurality of locations, a magnetic field induced by a circuit under test. A circuit drive module can energize the circuit under test to induce the magnetic field. Optionally, the circuit drive module detects an electrical response from the circuit under test. Optionally, magnetic field data is combined with electrical response data prior to outputting the test result.

Abstract: According to embodiments, multi-axis magnetic sensors (magnetometers) are disposed in an array or a plurality of arrays. The magnetic sensors can be disposed on modules that form the array. The magnetic sensors can each sense a local magnetic field coincident with the respective sensors. Data corresponding to the local magnetic fields can be analyzed by a magnetic field analysis circuit and assembled to form an image corresponding to the sensed magnetic field(s). The magnetic field analysis circuit can output the image corresponding to near-field magnetic features.

Abstract: Several methods, devices and systems for correcting rolling shutter artifacts are described. In one embodiment, an image capturing system includes a rolling shutter image sensor that may cause a rolling shutter artifact (e.g., warping). The system includes a processing system that is configured to perform an automatic rolling shutter correction mechanism that utilizes calibration data based on a relationship between pixel locations in an image plane of the image sensor and their corresponding rays of light in a coordinate space. The rolling shutter mechanism determines pixel velocity components based on the calibration data and estimates for each image an aggregate pixel velocity based on an aggregation of the pixel velocity components.

Abstract: The invention comprises a novel pet puzzle toy and food dispenser in which treats are located in receptacles wherein retrieval requires the pet to both spin and rock the puzzle in order to obtain the food. Much like a child's teeter totter, the food will end up in the receptacle with the greater weight as a result of pressure applied by a pet. The pet is both rewarded and entertained.

Abstract: The invention comprises a novel pet toy and treat trainer wherein plastic interlocking pieces simulate vertebrae of perceived prey. Edible discs are integrated alternately with the interlocking vertebrae so that an animal can “catch and consume” the simulated prey. The pieces reside on an inner frame of rope so that the entire toy is pliable. An animal head and tail make up the front and rear interlocking pieces and are also constructed of chewable, but non-edible materials.
