A system for providing a user with historical sales data for a plurality of vehicles comprising a fleet, the system comprising: (a) a database configured to store actual sales data for a plurality of vehicles that have previously been sold; and (b) a computer in communication with the database, the computer being configured to create a page for display to a user, the page including a display of a plurality of historical sales prices for at least one vehicle type that is similar to a user-selected vehicle type, wherein the displayed historical sales prices are calculated from the stored actual sales data and comprise historical sales prices for the at least one similar vehicle type that have been normalized to an average time of sale odometer reading. Also disclosed herein is a computer-implemented method for selecting which of a plurality of vehicles within a fleet are to be deleted from the fleet; the method comprising: (a) displaying, on an electronic page presented to a computer user, a value analysis for at least one type of vehicle within a rental vehicle fleet; (b) providing at least one link on the electronic page for selection by the user to initiate a deletion from the fleet of at least one fleet vehicle corresponding to the at least one vehicle type; and (c) responsive to user selection of the at least one link, displaying a list of fleet vehicles for selectable deletion from the fleet by the user, the listed fleet vehicles corresponding to vehicles of the at least one vehicle type.

In a headlight including a housing supporting a reflector with a bulb and having an opening for handling the bulb, a hood of elastic material is provided, which closes the opening from the rear side of the housing. An annular sealing lip is provided on the hood itself which in assembly lies against the outer surface of the conical ring portion formed on the rear wall of the housing. An open hinge with bellows and a tongue, engageable with a shoulder on the rear wall of the housing, is provided at one side of the hood and a snap arrangement is provided on a diametrically opposite side of the hood to secure the hood to the housing.
摘要:
A system for providing a user with historical sales data having relevance to a plurality of vehicles comprising a fleet for assisting users with defining residual values for fleet vehicles and performing cost going forward analyses and/or depreciation analyses of fleet vehicles. In one embodiment, such data can be useful for performing long term fleet planning wherein a computerized system is configured to determine a quantity of vehicles to be purchased during a future predetermined time period for inclusion in a vehicle fleet in response to a variety of user inputs.
摘要:
In a method and apparatus for determining the moisture content of a material with a measuring line extending through the material and having a proximal end connected to a signal generator for supplying a pulse signal to the measuring line, which pulse signal is reflected and returned back to the proximal end of the measuring line to which a comparator is connected for measuring the travel time of the signal supplied, and the reflected signal returned, to the proximal end of the measuring line and its amplitude is with compared with an amplitude corresponding to a threshold, an adjustable threshold value generator and controller are provided generating a threshold value signal which depends on the amplitude of the reflected signal.

A device for the fine adjustment in all three directions in space of an instrument arranged on a base by means of an actuating member. The actuating member consists of a handle the turning of which acts, via a universal joint, on the parts of the base adapted to provide vertical displacement of the instrument, and of an inner lever which when moved around the pivot point defined by the universal joint effects the horizontal displacement of the instrument with respect to a base plate. The inner lever is swingable towards all sides in a sleeve firmly connected with the base and its lower end is adapted with a ball foot which rests directly on the base plate. The bearing sleeve of the inner lever is arranged in or near the plane of the cardan joint; the radius of the ball foot corresponds to the distance between the bearing sleeve and the base plate.

A head rest for instruments used for opthamological examination comprises two vertical columns mounted on the instrument base. Each of said columns carries a vertical post to which is attached a forehead rest spanning the space between the posts. Said posts are retracted with respect to said columns. Said columns also carry a transverse bar spanning the space between the columns and supporting a chin rest which is adjustable with respect to the base. The arrangement provides maximum freedom of movement around the patient's eyes for the physician or surgeon.
