Laminate trim bit
Router bit for the processing of veneered surfaces (laminate trimming).
Laser rangefinder
Rangefinders based on the laser principle function as follows:
To begin with, the laser beam is aimed at the target point. The measuring process is started by sending a laser pulse in the direction of the target. The laser pulse is reflected by the target and received by a measuring device (photocell) in the laser rangefinder. Since the speed of light of the laser beam remains constant and is stored in the laser rangefinder, the time span between the emission and reception of the laser pulse can be used to calculate the exact distance to the target. In practice, the measuring process consists not of one single pulse, but of a series of laser pulses whose results are averaged and digitally displayed. Precondition for a successful measurement is a reflecting target and an undisturbed line of sight between rangefinder and target.
Rain, fog, smoke, but also strong sunlight shining on the laser rangefinder and/or the target can affect the measuring process.In addition to measuring simple lengths or distances, the rangefinder is also capable of multiple measurements (length, width, height) and with the appropriate calculations by the built-in processor you can calculate the surface area or volume. By applying the laws of angular geometry (Pythagorean theorem), the BOSCH laser rangefinder is capable of calculating a third length on the basis of two linear measurements.

Light alloy
Common name for metals which are lighter than iron and steel, such as aluminium, magnesium and their alloys.
Lithium-ion technology
Today´s lithium-ion batteries represent the state of the art in the development of rechargeable batteries. They are not affected by the memory effect and can therefore be charged up at any time without reducing their capacity.
With 90 to 110 Wh/kg, they have the highest energy density in relation to weight and volume in comparison to conventional rechargeable batteries such as NiCd or NiMH.
Lithium-ion cells have a voltage of 3.6 V instead of the 1.2 V in NiCd-or NiMh batteries. This is due to the special materials involved. A lithium compound consisting of cobalt-, manganese- or nickel-oxide or of a mixture thereof is used for the cathode electrode. The anode is made of a graphite compound. The insulation between the two electrodes consists of a micro-permeable plastic membrane. A dissolved lithium ion salt in organic solvent is used as electrolyte.
For reasons of safety lithium-ion batteries are equipped with a pressure release valve and a particularly pressure-resistant casing.
The charging process must be performed with utmost precision and is therefore controlled by special electronic components. They prevent an excessive current flow, control the charging and discharging characteristics and protect against overheating.
