In one aspect, a gloving light includes a plurality of light emitting diodes (LEDs) arranged in an array; a programmable controller configured to store logic including instructions for controlling a functionality of the plurality of LEDs; at least one user interface for modifying the logic stored in the programmable controller; and a housing configured to enclose the electronics and be retained in a digit of a glove. In another aspect, a gloving light includes at least one LED; at least one integrated circuit configured to store logic including instructions for controlling a functionality of the at least one LED; a user interface for modifying the logic stored in the at least one integrated circuit; a housing configured to enclose at least one integrated circuit and to be inserted into a digit of a glove; and a bidirectional communication interface comprising one or more wireless emitters and receivers for bidirectional communication.

Portable light providing plural beams of laser light

A portable light may comprise: a light body having an illumination, e.g., white, light source and one or more laser light sources, each light source being selectively energizable for producing light; and a switch for selectively energizing the illumination light source and/or the laser light sources. The one or more laser light sources provide diverging narrow beams of laser light, so as to appear as spaced apart dots or spots of laser light on objects illuminated by the beams of laser light. Because the laser light beams diverge, the distance between the dots is proportional to the distance to the object which the dots illuminate. A TIR optical element may also be disposed in front of the illumination light source for receiving the light produced thereby.

Collision Risk Mitigation Pedestrian Light Emitter
20200349816 · 2020-11-05 ·

A collision risk mitigation pedestrian light emitter is a safety device through which a pedestrian's presence is visually signaled to a vehicle operator to decrease collision potential. The safety device includes a first telescoping leg, a second telescoping leg, a light-emitting device, a power source, and a locking mechanism. The first telescoping leg and second telescoping leg are terminally and hingedly connected to each other to form an L-shaped structure. The locking mechanism secures the L-shaped structure and is mechanically integrated between the first telescoping leg and second telescoping leg. The light-emitting device visually indicates the pedestrian's presence and is adjacently mounted to the first telescoping leg to enable variable light height adjustment. The light-emitting device is powered by and electrically connected to the power source mounted to the first telescoping leg. The second telescoping leg is used to mount/attach the safety device to the pedestrian, preferably to a backpack.

Device with a mid-frame structure and reverse draft

An electronic reading device includes a mid-frame structure such that the mid-frame structure can include a reverse draft. A reverse draft corresponds to a back of the electronic reading device being a predetermined amount wider than a front of the electronic reading device. Additionally, a co-molded mid-frame stiffener provides a predetermined rigidity of the electronic reading device. The electronic reading device also includes a display integrated with the front of the mid-frame structure, wherein a space between the display and the mid-frame structure includes one or more electronic reading device components. Similarly, a back cover is integrated with the back of the mid-frame structure, wherein a space between the back cover and the mid-frame structure includes additional electronic reading device components.
