A wearable electronic device includes a body having a first battery and a port electrically connected to the first battery, a band having a connector and a set of first conductors electrically connected to the connector, and a belt having at least one second battery, a set of second conductors and an input port electrically connected to the second battery. The band is connected to the port via the connector so as to be electrically connected to the body. The belt may removably attach to an outer surface of the band, and the second battery may transmit power to the first battery by combining the two sets of conductors. When the belt is removed, the power consumed by the second battery is replenished by an external power source connected to the input port, mastering the information at any time.

A composite film includes a substrate that is not responsive to relative humidity, and also one or more layers of hygromorphic material. The hygromorphic material expands in response to an increase in relative humidity and contracts in response to a decrease in relative humidity. In some cases, the composite film is bi-layer or tri-layer. The composite films are fabricated such that they undergo a desired bending pattern in response to changes in relative humidity. In some cases, these bending patterns are combinations of two bending primitives: a smooth curve and a sharply angled curve. These two primitives are combined to create a variety of shape transformations including 1D linear transformation, 2D surface expansion and contraction, 2.5D texture change and 3D folding. Any type of hygromorphic material may be employed, including living gram positive and gram negative bacterial cells, yeast cells, plant cells, mammalian cells, cell debris, or hydrogel.

Antibodies having specific binding for the parent THC (Δ9-THC) and its major metabolites are provided which present a significant increase in sensitivity of immunoassays such as lateral flow immunoassays and ELISA for THC. The present invention also provides a rabbit hybridoma producing the antibody as a monoclonal antibody, a recombinant antibody, further molecularly engineered recombinant antibodies against parent Δ9-THC and its metabolites and cell lines producing the recombinant antibodies. The invention also provides applications of the antibody in immunoassays, particularly lateral flow immunoassays, specifically applications in detecting THC in body fluids, particularly saliva, and kits for determining the presence of THC.

A disposable dental angle with a one-piece hollow housing, having the axis of its head section angled obtusely with respect to the axis of its tail section, is provided. The obtusely angled front aperture of the head section of the housing allows insertion of a driven rotor such that the driven rotor is positioned with an obtuse angle to the driving shaft in the end aperture of the tail section of the housing. The obtuse angle structure facilitates teeth cleaning operations by allowing the dental angle to easily reach all areas of the mouth and making practitioners feel more comfortable by allowing to maintain an ergonomically correct neutral wrist position and therefore reducing hand fatigue. A horseshoe-like snap retainer fits within the head section of the housing over the driven rotor to retain the rotor from coming out. A similar horseshoe-like snap retainer fits within the tail section of the housing over the driving shaft to retain the shaft firmly such that the gear of the driven rotor is always properly coupled to the matching gear of the driving shaft. The driving shaft transfers the rotation from a dental tool to the driven rotor for the purpose of tooth prophy using a cleaning cup.

A device for mixing two paste components, such as a dental impression substance and a catalyst, comprising a tubular housing, two inlet openings for the two paste components to be mixed, and an outlet opening for delivering the mixed paste, is presented. The housing consists of a premixing chamber at the front end and a tubular mixing chamber at the rear end. The two paste components are mixed first in the premixing chamber by a dynamic rotor and then mixed in the tubular mixing chamber by a twisted static shaft, resulting in a well mixed, bubble-free paste at the outlet opening of the housing.

A disposable, securely retained dental angle is provided. The angle includes a one-piece hollow housing having a short leg at its front end, which is angled with respect to the long leg. Both the short and long legs have a through bore. The short leg has an aperture, which is connected to the bore of the long leg to allow insertion of a driving shaft through the short leg of the angle. A driven rotor is inserted in the short leg. A horse-shoe-like snap rotor retainer fits within the short leg over the driven rotor to retain the driven rotor in the angle. A paw-like or, alternately, a horse-shoe-like locking means fits within the long leg over the driving shaft to lock the driving shaft in the angle and to retain the angle together. In one embodiment, a pair of splinters on the driven rotor provides the function to retain the rubber prophy cup firmly while the driven rotor is in operation.
