A vehicle leveling system including at least one level sensor, a controller and an output. The sensor measures how level the vehicle is relative to horizontal. Optionally, it does so dynamically, as the vehicle moves across a potential parking area. The controller analyzes the sensor measurements, and informs the operator via the output whether the vehicle is level in a given direction, whether the vehicle is leveling, whether the vehicle can be leveled at a given location, and/or the “best” leveling that the system is capable of at a location. The system also may automatically level the vehicle relative to the ground for the operator. In one embodiment, the leveling system communicates with an existing vehicle electronic height control system. The leveling system overrides or controls the normal operation of this system, and uses it to level the vehicle, for example, by adjusting the vehicle suspension.

A system and method for measuring distances related to a target object depicted in an image and the construction and delivery of supplemental window materials for fenestration. A digital image is obtained that contains a target object dimension and a reference object dimension in the same plane. The digital image may contain a target object dimension identified by an ancillary object and a reference object dimension in different planes. Fiducial patterns on the reference and optional ancillary objects are used that are recognized by an image analysis algorithm. Information regarding a target object and its immediate surroundings is provided to an automated or semi-automated measurement process, design and manufacturing system such that customized parts are provided to end users. The digital image contains a reference object having a reference dimension and calculating a constraint dimension from the digital image based on a reference dimension. The custom part is then designed and manufactured based on a calculated constraint dimension.

A dose counter for a metered dose inhaler includes a force sensor, an electronic controller, a memory for storing data indicative of a remaining number of doses and an electronic display device coupled to the controller for displaying the remaining number of doses. The dose counter is attached or integrated into a base of a canister containing medicament such that force applied to the base of the canister is registered by the force sensor, the controller being configured to measure force applied to the dose counter when depressing the canister and being responsive to measured force to decrement the remaining number of doses stored in the memory and shown on the display device.

A container crane includes a movable trolley and a load-carrying frame pendantly connected to the trolley and comprised of a spreader and a head block, for transfer of a container from or to a transport vehicle. Plural optical detectors are mounted on the trolley for identifying longitudinal and transversal edges of the head block or spreader and the transport vehicle. Operatively connected to the detectors is a processing device for determining a spatial position of the edges and calculating a position of longitudinal and transversal center lines of the head block or spreader and the transport vehicle and their spatial positions in relation to one another. In this way a possible offset of the center lines of the head block or spreader with regard to those of the transport vehicle in longitudinal and transversal directions as well as a rotation angle of the center lines can be determined, whereby a detected offset or rotation angle is compensated by displacing the spreader relative to the head block.

A drill for dental implant is disclosed to include a connection head configured for quick connection to a dental handpiece, a round bur, and a series of active drill body portions of different diameters connected between the connection head and the round bur, said active drill body portions in an order from the smallest diameter to the largest diameter in direction from the round bur toward the connection head.

A method, apparatus and kit for precisely and accurately determining the volume of a liquid aliquot which can be used to calibrate a liquid delivery device. Two dye-containing solutions, a sample solution and a diluent solution, are prepared such that each solution contains a different dye, with the solutions having different absorbance values at a first wavelength and at a second wavelength. The absorbance value of a known volume of diluent solution is measured at both wavelengths. Either one aliquot of sample solution is added to the diluent solution and then absorbance measurements are made at both wavelengths, or multiple aliquots of sample solution are mixed serially into the diluent solution and then absorbance measurements are made at both wavelengths after each aliquot is added. The volume of any single aliquot is calculated by using a two-step formula which is based on the Beer-Lambert law.

A method of error compensation in a chromatic point sensor (CPS) reduces errors associated with varying workpiece spectral reflectivity. The errors are associated with a distance-independent profile component of the CPS measurement signals. Workpiece spectral reflectivity may be characterized using known spectral reflectivity for a workpiece material, or by measuring the workpiece spectral reflectivity using the CPS system. CPS spectral reflectivity measurement may comprise scanning the CPS optical pen to a plurality of distances relative to a workpiece surface and determining a distance-independent composite spectral profile from a plurality of resulting wavelength peaks. By comparing the distance-independent composite spectral profile obtained from a workpiece with that corresponding to the CPS distance calibration procedure, the contribution of the reflectivity characteristics of the workpiece will be indicated in the differences between the profiles, and potential CPS position errors due to varying workpiece reflectivity characteristics may be calculated and/or compensated.

This invention relates to a method of associating or re-associating devices in a control network including control zones to respective zone controllers (ZCs) controlling the control zones. In a first step, an associating or re-associating timer (ZC_REASSC_TIMER) window is initialized at the (ZCs) defining the time during which said associating or re-associating of the devices takes place. In a second step, during the (ZC_REASSC_TIMER) window zone specific information (ZN_SPEC) message sage is transmitted, the (ZN_SPEC) message including information about the devices expected to be in the zones controlled by the (ZCs). In a third step, it is compared whether the zone specific information contained in the (ZN_SPEC) received by the devices includes device specific information that match with local device specific information associated to the devices. In case the comparing results in that a pre-defined matching criteria is fulfilled an association or re-association request message (RA_REQ) is sent from the devices to the zone controllers (ZCs) where the pre-defined matching criteria was met. The (RA_REQ) message including device description parameters and indicates a request from the devices to join the control zones controlled by said (ZCs). Finally, it is determined whether the association or re-association of the respective devices is to be confirmed by means of comparing, by the respective (ZCs) receiving the (RA_REQ) message, the device description parameters included in the (RA_REQ) message match with zone specific information included in the (ZN_SPEC).

An improved compression wire joint is disclosed that allows for tighter connections between the wires. It is particularly useful for connecting copper and aluminum wires together because it provides a tight connection that better accommodates thermal expansion of each wire.

An optical retimer is provided that retimes an optical data signal entirely in the optical domain, thus eliminating the need for optical-to-electrical and electrical-to-optical converters, which are needed to perform retiming in the electrical domain. Eliminating these conversion steps also eliminates, or at least decreases, the potential for errors in the retimed optical signal, such as jitter. The optical retimer samples the optical data signal during a clock cycle that has been determined by clock recovery, allows the sampled signal to traverse an optical pathway for the remainder of the cycle, out-couples a fraction of the sampled optical signal each time the signal traverses the optical pathway, and amplifies the signal traversing the pathway to maintain the signal at the power level it had when it was sampled. By the end of the clock cycle, the out-coupled signal corresponds to a retimed version of the original signal, synchronized to the recovered clock signal.
