Patent number: 11846384Abstract: A tilt angle adjustment mechanism capable of both discrete and fine adjustment includes a bracket, a housing tiltably connected to the bracket and a wheel disposed between the bracket and the housing and rotatably connected to the bracket. A spiral guiding member is provided on the wheel and engages with a curved row of evenly spaced detents at the housing to fix the housing to the wheel at plural predetermined tilt angles defined by the detents to achieve discrete tilt angle adjustment of the housing, and rotation of the wheel drives the spiral guiding member to slide through the curved row of detents and causes the tilt angle of the housing to continuously change with the rotation.Type: GrantFiled: November 22, 2022Date of Patent: December 19, 2023Inventor: Shiu-Fai Stephen Man

Publication number: 20190098731Abstract: A programmable flashlight with automatic light intensity adjustment means includes a flashlight casing, a light source, a programmable switch, a printed circuit board with a microprocessor coupled thereon, a power source and a sensor component. A light controlling program operable by the microprocessor is adapted to control electrical current passing through the light source according to intensity of incident light as detected by the sensor. A programming program operable by the microprocessor is adapted to control the programming of the functional sequence of the programmable switch and/or the parameters of each of the operation modes by sensing a sequence of ON and OFF light flashes as generated by an external device.Type: ApplicationFiled: November 28, 2018Publication date: March 28, 2019Inventor: Shiu-Fai Stephen MAN

Patent number: 8368317Abstract: A flashlight with momentary function and multiple lighting modes wherein a mechanical switch is activated by a pushbutton so that each depression of the pushbutton causes the switch to cycle through a first state, a second state and a third state sequentially. When the switch is in the first state or the second state, it is electrically connected to the respective port of the integrated circuit and the integrated circuit drives the light source to operate in the respective lighting mode; when the switch is in the third state, it is electrically disconnected from the integrated circuit and the integrated circuit drives the light source to operate in a third lighting mode. When the integrated circuit detects that the switch is disconnected from the integrated circuit after a state which corresponds to the OFF mode and is therefore transitioning to a subsequent state, it drives the light source to operate in the lighting mode of the subsequent state.Type: GrantFiled: December 23, 2010Date of Patent: February 5, 2013Assignee: Kaper Industrial LimitedInventor: Shiu-Fai Stephen Man
