A clamping mechanism for mounting and demounting bicycle components of at least partially muscle-powered two-wheeled vehicles such as bicycles, including at least one operating lever and a clamping component. The clamping mechanism includes two clamping parts, one of which clamping parts is a clamping sleeve and connected with the operating lever, and another of which clamping parts is formed at the clamping component. The operating lever can be moved from an engagement position; in which it is non-rotatably connected with the clamping component to a rotary position in which it is freely rotatable relative to the clamping component. In the rotary position, the operating lever is disposed closer to the clamping component than in the engagement position.

A three-dimensional display device comprises a display panel, a parallax barrier, an acquisition section, a memory, and a controller. The display panel displays a parallax image and emit image light corresponding to the parallax image. The acquisition section successively acquires a plurality of pieces of positional data indicating user's eye positions from a detection device which detects eye positions based on photographed images which are successively acquired from a camera which images user's eyes at imaging time intervals. The memory stores pieces of positional data which are successively acquired by the acquisition section. The controller is configured to output predicted eye positions of the eyes as of a time later than the current time based on the positional data pieces stored in the memory, and cause each of subpixels of the display panel to display the parallax image, based on the predicted eye positions.

A system and method in a building or vehicle for an actuator operation in response to a sensor according to a control logic, the system comprising a router or a gateway communicating with a device associated with the sensor and a device associated with the actuator over in-building or in-vehicle networks, and an external Internet-connected control server associated with the control logic implementing a PID closed linear control loop and communicating with the router over external network for controlling the in-building or in-vehicle phenomenon. The sensor may be a microphone or a camera, and the system may include voice or image processing as part of the control logic. A redundancy is used by using multiple sensors or actuators, or by using multiple data paths over the building or vehicle internal or external communication. The networks may be wired or wireless, and may be BAN, PAN, LAN, WAN, or home networks.

An optoelectronic device, in particular a display device, comprises: at least one optoelectronic light source, an at least partially transparent front layer, an at least partially transparent support layer, wherein the light source is arranged between the front layer and the support layer, wherein a front side of the light source faces the front layer and a rear side of the light source faces the support layer, and wherein a limiting device is provided in a circumferential direction around the light source, wherein the limiting device limits a spatial region, in which the light source emits light such that total internal reflection of the emitted light, in particular at an interface between the front layer and the outside, is avoided or at least reduced.

An information display system configured to unidirectionally display an image to inside or outside of a space via a transparent projected member provided in the space includes an image projection apparatus arranged inside the space and configured to generate and project image light by modulating a light flux from a light source, a transparent sheet provided on an inner surface of a display region set on a part of the projected member, and a light direction changing panel configured to change a direction of the image light from the image projection apparatus toward the transparent sheet of the display region, and the transparent sheet includes a retardation plate, an absorption type polarization plate that absorbs a specific polarized wave, and a transparent diffusion sheet material having a light diffusion function, and projects the image light whose direction has been changed by the light direction changing unit to the inside or the outside of the space.

A wheel disc including a bolt hole for bolt fastening, includes a first region extending to have a predetermined width in a circumferential direction of the bolt hole and a second region, other than the first region, wherein the first region has an average tensile strength lower than that of the second region.

A display device includes an electronic control unit configured to: obtain a traveling plan from an automatic driving system of a vehicle, the traveling plan including a course of the vehicle under automatic drive control of the automatic driving system; obtain, from the automatic driving system, a system confidence level of the automatic drive control calculated based on at least an external environment around the vehicle; and display, on a display, a pointer as an image indicating the course during the automatic drive control in a display mode set based on the system confidence level.

A wheel for a vehicle, which includes a mount configured to mount the wheel to a hub of the vehicle; a colored surface that is hidden from direct view from an outside environment when the wheel is mounted to the hub; and a contoured reflective surface optically aligned to reflect the colored surface into view of the outside environment when the wheel is mounted, thereby appearing to alter a color of the reflective surface.

A sun visor mask holder includes an attachment device for attaching the sun visor mask holder to a sun visor. A mask holder holds a mask in a stretched out position. The mask holder includes base section that includes a first hook for holding a first end of the mask. A slider section includes a second hook for holding a second end of the mask. A slider knob allows the slider section to be adjusted with respect to the base section adjusting a distance between the first hook and the second hook to accommodate holding masks of different sizes.

A wheel assembly is provided that includes spokes having one or more triangular prisms positioned between inner and outer surfaces of the spokes that impart additional strength.
