Abstract: Knives, handles for knives, and a method for making a knife are disclosed. In one example, a knife comprises a handle that includes a flat top surface, two upper chamfers, a flat bottom surface, and two curving sides. The top surface, the two chamfers, bottom surface, and two sides form a six-sided cross section shape. The width of the handle further varies along its length. A blade fastened to the handle comprises a tip at a distal end and a pinch radius configured to accommodate a user's finger. A spine is continuous with the handle's top surface and tapers from the handle to the tip. A cutting edge tapers along the length of the blade from the pinch radius to the tip. A bolster is between the handle and the blade and comprises a six-sided cross section shape that substantially matches the shape of the handle.

Abstract: Cosmetic blending devices for producing a cosmetic liquid from a solid-shell cosmetic ingredient capsule. The cosmetic blending devices include a lid, a base, a blending element configured to blend the capsule, and a drive mechanism configured to actuate the blending element. The cosmetic blending device may include a thermal element configured to change a temperature of the capsule. The thermal element may melt the capsule. The solid-shell cosmetic ingredient capsule comprises a shell defining an enclosed inner volume, and cosmetic material included in the enclosed inner volume. Methods of using the cosmetic blending devices comprise placing the solid-shell cosmetic ingredient capsule into the cosmetic blending device and blending the capsule to produce the cosmetic liquid. Methods of forming the solid-shell cosmetic ingredient capsule comprise forming a portion of the shell, adding the cosmetic material to the portion of the shell, and forming the remaining portion of the shell.

Abstract: Systems and methods for measuring and indicating brush head life are disclosed. In one embodiment, the system includes a brush head that moves with respect to a brush handle; an energy harvester that generates electrical signals based on movements of the brush head; a controller in electrical communication with the energy harvester; and an indicator in electrical communication with the controller. The indicator is energized based on a signal from the controller.

Abstract: Systems, methods and computer readable memory devices for delivering a presentation are provided. In one example, a method includes establishing a wireless network access point that creates a closed wireless network. An encrypted communication session is established via the closed wireless network with a plurality of client computing devices. A virtual network server is run on the host computing device, and each of the client computing devices is communicatively coupled to the virtual network server. A subset of the plurality of client computing devices is selected, and audio/video data is streamed to only the subset of the client computing devices.

Abstract: The disclosed technology relates to antenna configurations for wireless power transmission and supplemental visual signals. In some implementations, the disclosed technology includes a wireless power transmitter with boards that have multiple antennas physically coupled to the board. In some implementations, the antennas boards are arranged in a polygonal configuration (e.g., star shape). Additionally, in some implementations, the antennas can have different polarization configurations.

Abstract: End effectors and systems including end effectors configured to provide colorimetric indicia of a wear state of the end effector are described. In one embodiment, the end effector includes: a base portion coupleable to a motor; a chamber including an optically translucent window and a chamber interior; and a flowable material disposed in the chamber interior and having a color. The end effector is configured to provide colorimetric indicia of a wear state of the end effector based at least in part on mixing of the flowable material.

Abstract: End effectors and systems including end effectors configured to provide audible and/or haptic indicia of fatigue failure of springs disposed in the end effectors are described.

Abstract: End effectors and systems including end effectors configured to provide visible indicia of a wear state of the end effectors are described.
