Abstract: A vertical-cavity surface-emitting laser (VCSEL) array may include an n-type substrate layer and an n-type metal on a bottom surface of the n-type substrate layer. The n-type metal may form a common anode for a group of VCSEL. The VCSEL array may include a bottom mirror structure on a top surface of the n-type substrate layer. The bottom mirror structure may include one or more bottom mirror sections and a tunnel junction to reverse a carrier type within the bottom mirror structure. The VCSEL array may include an active region on the bottom mirror structure and an oxidation layer to provide optical and electrical confinement. The VCSEL array may include an n-type top mirror on the active region, a top contact layer over the n-type top mirror, and a top metal on the top contact layer. The top metal may form an isolated cathode for the VCSEL array.

The brush head may include bristles, the brush head releasably securable to the first end region of the handle. The rechargeable battery may be in the volume. The electric motor may be at least partially disposed in the volume, the electric motor in electrical communication with the rechargeable battery, the electric motor in mechanical communication with the brush head. The pair of electrical contacts may be in electrical communication with the rechargeable battery, and the pair of electrical contacts axially and radially spaced from one another, relative to the longitudinal axis.

Abstract: Devices, systems, and methods of the present disclosure are generally directed to facilitating user control of high-pressure flow of liquid for oral irrigation carried out as part of personal dental care. Such control over high-pressure flow may reduce the likelihood of errant spray of liquid outside of the user's mouth (e.g., onto mirrors, countertop surfaces, or the user's clothes). Such improved control over errant spraying may reduce the potential for frustration and, thus, may promote maintaining oral irrigation as part of a personal dental care routine. Further, or instead, through facilitating user control of high-pressure flow of liquid, the devices, systems, and methods of the present disclosure may improve the effectiveness and efficiency of self-administered oral irrigation in promoting a user's oral hygiene.

Abstract: A razor handle. The razor handle can have a main body and a pivoting head pivotally coupled with the main body about a first axis of rotation. A severable benefit delivery member can extend from a main body connection on the main body to a pivoting head connection on the pivoting head, the benefit delivery member providing a first biasing torque on the pivoting head to affect an angular deflection about the first axis of rotation of the pivoting head relative to the main body. A spring member can extend from a spring-main-body connection on the main body to a spring-pivoting-head connection on the pivoting head, the spring member applying a second biasing torque to affect an angular deflection about the first axis of rotation of the pivoting head relative to the main body.

Abstract: A razor handle. The razor handle include a main body and a pivoting head pivotally coupled with the main body about a pivot axis. The pivoting head can have a substantially trapezoidal prism shape and can include a base member and a cover member that overlies the base member in a mating relationship and can have an internal compartment. The cover member can have a skin interfacing face.

Abstract: A handle for a personal care system with a first end having a head configured to engage a shaving cartridge, a second end with a partially enclosed ring having a first arm with a first end facing a first end of a second arm to defines a gap having a width. The first and second arms define an undercut region below the gap. A lower surface extends between the partially enclosed ring and the head, wherein the lower surface and the partially enclosed ring are configured to receive a container.

Abstract: Disclosed herein are efficient mechanical fuse devices that are capable of functioning at high current levels. These devices comprise mechanical features configured such that the fuse devices have a non-triggered state, which allows current to flow through the device, and a triggered state, which does not allow current to flow through the device. In some embodiments, the devices are configured such that a certain pre-determined current level flowing through the device will generate a sufficient electromagnetic field to cause the mechanical elements to transition the fuse device into the triggered state and thus interrupt a connected electrical circuit, device or system. In some embodiments, these devices can also comprise hermetically sealed components. In some embodiments, the fuse devices can comprise pyrotechnic features.

Abstract: Electrochemical devices with metal casings have been considered incompatible with nuclear magnetic resonance (NMR) spectroscopy because the oscillating magnetic fields (“rf fields”) responsible for excitation and detection of NMR active nuclei do not penetrate metals. According to the present invention, rf fields can still efficiently penetrate into nonmetallic layers of electrochemical cells (such as a coin cell battery configuration) provided the magnetic field is oriented tangentially to the electrochemical cell electrodes in a “skimming” orientation. As an example, noninvasive high field in situ 7Li and 19F NMR of an unmodified commercial off-the-shelf rechargeable coin cell was demonstrated using a traditional external NMR coil setup. The in operando NMR measurements revealed that irreversible physical changes accumulate at the anode during electrochemical cycling.
