Abstract: A laser crossline device suitable for construction includes at lease a first and a second laser beam produced by diode modules. The diode modules revolve around a horizontal axis so as to form a 360.degree. laser scanning plane that is perpendicular to the horizontal axis of the module. The plane can be adjusted with a bubble level and an adjustment screw. The two modules are situated so as to generate planes that intersect at a right angle. The line of intersection forms a plumb line. If desired, a third orthogonal plane can be added to the device. A single rotary motor drives all of the diode modules.

Abstract: A combination of square alloy rulers with precisely machined planes, each ruler unit having two 1.5v batteries and two bubble levels to level in all directions. A line generator is mounted in front of a laser diode module. This basic laser line ruler unit can produce an accurate laser level line or plumb line after it is calibrated. By adjusting the calibrating knob, the laser line ruler will produce a precise level line or plumb line when the level bubbles are centered. Putting a properly aligned level line unit and a properly aligned plumb line unit together will produce a cross line in front of the combination. Adding at least one more laser line ruler, that is combining three or more line units, will produce 90.degree. lines, 45.degree. lines, and 180.degree. lines, as well as 270.degree. lines up and down or on the right and left sides by simply adjusting the position of the relevant ruler. The housing of the ruler unit is machined with accurate planes and vertical angles. Therefore, the combination of several rulers can project accurate level lines, vertical lines, 45.degree. lines, 90.degree. lines, etc. This simple, small, and unique ruler combination is affordable to the public and can be widely used in hardwood layout and cutting, carpet cutting, squaring the surfaces of any plane object, etc. in addition to its usage in construction.

Abstract: The present invention relates to laser leveling device suitable for construction. The present invention uses a standard low cost laser diode module as the laser source and optical system. A novel method is provided to align the non-collimated beam emitted from the standard low cost laser diode module so that it is perpendicular to the rotational axis of the laser level. The present invention describes a laser level which can be operated in four different modes: dot mode, line mode, oscillation mode and plane mode. Dot mode provides two level laser dots. Line mode provides a short bright level line. Oscillation mode provides a long bright reference line. Plane mode provides a level 360 degree reference plane. The invention also provides a structure which allows two vertical reference planes which are perpendicular to each other and perpendicular to the horizontal reference plane to be generated.

Abstract: A remote starting device intended chiefly for use in cars that utilizes a pulse signal that is generated by either an RF transmitter, a keypad, or a telephone. The pulse signal is transmitted to a rotating drive attached to the subject ignition. When the device receives the pulse signal, the rotating drive rotates to activate the ignition of the car, thereby starting the engine. The remote starting device operates independently of the car's circuitry using only the car's battery, via the cigarette lighter, as a power source. There is no need to modify the car's electrical system to install the device. This greatly simplifies installation of the device and does not jeopardize any applicable warranty on the car.

Abstract: A low cost automatic laser level instrument uses a solid laser diode module as the laser source. It is not necessary to adjust the laser diode module to make the center ray align with the concentric axis. The only requirement is adjusting a reflecting mirror or prism so that the center ray is vertical to the rotating axis. In other words, any ordinary diode module can be used. The device levels automatically by using a knife edge that is propped up by a universal ring. The pendulum remains steady under the influence of a magnetic field. The magnetic field functions as a damper, which stops the swinging of the pendulum very quickly. After adjusting the center ray to be perpendicular to the pendulum (which points to the earth's core), the device will produce a standard level line.
