A wireless network permits wireless devices to determine their own location and receive location-based services. The network includes a communication server coupled to a plurality of access points and at least one mobile wireless device that wirelessly communicates through the access points. Each wireless device includes a location table through which the wireless device can determine its physical location. The location table includes the physical location of the various access points indexed by their network addresses. When the wireless device communicates with an access point, the access point provides the wireless device its address. The wireless device uses the address of the access point as an index into the location table to determine its own location based on the location of the access point. Once the wireless device has determined its own physical location, it requests location-based services from or through the communication server.

At least one indicating device is also provided, which is impinged upon by the correcting variable of the distance measurement system (1,2) and which supplies an indication depending on the correcting variable. The indicating device comprises at least one tactile indicator (3) which is continuously or quasi-continuously displaced along a tactile path as monotone function of the distance measured by the distance measurement system (1,2). The tactile indicator can, for instance, comprise an adjustable element (3). The user can thus feel the distance measured by touching the position of the displaceable element (3).

Process for preparing glass-ceramic body including the steps of providing a basic glass body and subjecting the basic glass body to a thermal treatment whereby a crystalline phase embedded in a glass matrix is formed. The basic glass body is made of a composition comprising 65 to 72 wt-% SiO₂, at least 10.1 wt-% Li₂O and at least 10.1 wt-% Al₂O₃ based on the total weight of the composition, the proportion of Li₂O to Al₂O₃ being from 1:1 to 1.5:1. The thermal treatment involves a nucleation step followed by several crystallization steps at different temperatures, whereby at least two different crystalline phases are formed.

An illuminating device able to easily visualize a pedestrian, etc. on a footway by the driver of an automobile is provided. The illuminating device has a footway side light source portion for irradiating light of spectral characteristics rich in blue-green color light to the footway, and a roadway side light source portion for irradiating light of spectral characteristics rich in green-red color light to a roadway. Further, the spectral characteristics of the light irradiated from the footway side light source portion are set such that a value I_p obtained by the following formula (1) is greater than a value I_C obtained by the following formula (1) from the spectral characteristics of the light irradiated from the roadway side light source portion.

An improved retractor comprising one or more cheek positioning members and one or more lip positioning members has been developed. This retractor makes it possible to conduct X-ray CT or similar scans of the jaw and to construct anatomically accurate models of bone, teeth and gingival tissue. What is provided is an improved retractor useful when conducting CT scans of the jaw of an individual requiring a dental implant and models to be constructed that are anatomically accurate with respect to bone, teeth and gingival (soft) tissue. Drill guides, and prostheses are constructed with the jaw models.

A method is provided for the removal from a heat exchange of lint that is generated during a drying process in a domestic appliance for laundry care. A rinsing fluid is run through the heat exchanger for cleaning and the rinsing fluid is deflected during a cleaning phase with the magnitude of deflection or the direction of deflection of the rinsing fluid being a function of the strength of an air flow that is applied to deflect the rinsing fluid. The rinsing fluid is thus run through various regions of the heat exchanger depending on the deflection.

A flame sense circuit for a gas burner control employs a flame rod for flame rectification. An AC source applies an AC wave through a capacitor to the flame rod, and the flame rod is also connected via a resistive voltage divider to a DC voltage source. A voltage divider node is connected to a voltage follower, which impedance-matches an ADC input of a microprocessor controller. The flame sense circuit senses conditions of no-flame, and flame rod in contact with or leaking to ground, and when flame is present can quantify sensed flame as good, weak and marginal.

There is proposed a method that may be universally used for controlling a man-machine interface unit. A learning sample is used in order at least to derive and/or initialize a target action (t) to be carried out and to lead the user from an optional current status (e_c) to an optional desired target status (e_t) as the final status (e_f). This learning sample (l) is formed by a data triple made up by an initial status (e_i) before an optional action (a) carried out by the user, a final status (e_f) after the action taken place (a).

A multilayer enzyme immobilization process is provided comprising adsorbing a polyethyleneimine (PEI) solution in a fibrous matrix, and adding an enzyme to the fibrous matrix, which comprises a plurality of fibrils. The process further comprises forming at least two layers of PEI-enzyme aggregates on the fibrils, and cross-linking the multilayer PEI-enzyme aggregates. The process can further comprise washing the fibrils containing the cross-linked PEI-enzyme aggregates with distilled water and acetic acid buffer subsequent to cross-linking. However, the PEI-containing matrix is not washed prior to the addition of enzyme. The enzyme can be β-galactosidase and the fibrous matrix can be cotton cloth. The multilayer immobilized enzyme can be employed in a biocatalyst reactor for production of galacto-oligosaccharides from lactose and the hydrolysis of lactose to glucose and galactose.

A process for providing a topography to the surface of a dental implant, said surface being made of a ceramic material. At least a part of the surface of the dental implant is etched with an etching solution comprising hydrofluoric acid at a temperature of at least 70° C. Thereby, discrete grains or agglomerates of grains are removed from the ceramic material.

A slidable cargo area floor liner and cargo management device for a vehicle, and in particular, it is a substantially flat, rectangular sheet of material which is independent of the vehicle, which slidably moves on the floor of the cargo area of the vehicle and may be completely slidably removed from the vehicle. In addition, the device also provides protection to the floor of the vehicles cargo area, organizes cargo, and secures cargo through the use of a plurality of openings and tie down points integrated into the device. In use, the liner lies flat and occupies the cargo area of a vehicle without attaching itself to the cargo area or vehicle frame. The liner is equipped with a set of handhold openings that can be gripped and pulled towards the rear opening of the vehicle to access objects which would otherwise be difficult to reach. The liner is equipped with a plurality of openings that can be used as tie down points to assist in securing cargo in the vehicles cargo area and a rear catch all that ensures cargo remains on the liner.
