A contact element and a contact means comprising at least one contact element where the contact element comprises electrical contact means renders displaceable, such as translatable or rotatable, by a resilient means in which the conductor is at least partly embedded and through a surface of which the contacting means is exposed. This resilient means provides a contact element in which the contacting means may compensate for an unintentional displacement by one forcing the other in a given direction, via the resilient means. Also, the displacement may bring about a cleaning action between the contacting means. These means may be used both for disconnectable connections and rotatable, unconnnectable connections.

Means for providing electrical contact

An implant to be inserted into a bore or recess (,) of a bone, such as a jaw bone (,), comprises a radially expandable tubular member (,) which is preferably made from a helically wound string or wire, and a core member (,) to be positioned within the tubular member. The core member (,) may be moved axially in relation to the tubular member (,) so as to expand the tubular member radially, whereby the implant may be efficiently fastened. The core member (,) may be screwed into the outer tubular member (,) or into an anchoring member (,) arranged at the inner end of the recess (,). The implant is relatively easy to remove if such removal should become necessary by radially contracting the tubular member (,).

Method of fastening an implant to a bone and an implant therefor

A rechargeable battery includes one or more rechargeable cells and means for providing information to control charging. Information is provided in a form for being read or sensed by mechanical, optical, electromagnetic, or electronic techniques including combinations of these techniques. The information may indicate battery performance history, present state of the battery, and parameters for how it may be charged. As to performance history, the information may include, for the battery or a cell of the battery, indicia describing: one or more previous charging or discharging processes, of the last charging process, of the last discharging process, of the time period lapsed since the last charging or discharging process. The information may include indicia of the present charge state and condition of the battery or its individual cells. For controlling charging, the information may include indicia describing for the battery or an individual cell: the type, capacity, maximum charging voltage, maximum charging current, maximum temperature, or maximum inner pressure, a charging parameter or sequence of the charging parameter, or charging parameter algorithms. A charging parameter may indicate charging voltage, charging current, temperature or inner pressure of the battery or cell, the rate of change of any such parameter, the parameter as a function of elapsed charging time, or a combination thereof. A sequence for a charging parameter may indicate values over time representing charging processes for various initial charge states of the cell or battery.

Battery system providing indicia of a charging parameter

In order to optimally control the charging of a rechargeable battery of one or more cells to ensure that full and rapid charge is achieved without damaging the battery, a maximum safe value (or sequence of values during the charging process) for one or more charging parameters is determined during a test charge, and subsequent charges of the battery are performed without exceeding the predetermined maximum value(s) for the charging parameter(s). Among the charging parameters contemplated for use are: the charging voltage potential placed across the battery terminals, the charging current supplied to the battery, the temperature of the battery cell and internal pressure of the battery cell as well as rates of changes of the parameters. In accordance with apparatus for practicing the invention, the value(s) of one or more predetermined maximum parameters are stored, and the corresponding actual charging parameter values are measured during the charging process and compared to the stored values to develop signals for controlling the charging process and thereby maintain the monitored parameter(s) no higher than the predetermined maximum value(s).

An inhaler comprises a tubular body in which an air flow passage is defined. A single dose of an active, inhalable, particulate substance is arranged within the air flow passage and is sealed or closed in relation to the ambient atmosphere by closure means, such as removable caps, a section of the flow passage extending from a free mouthpiece end of the tubular body along a major part of the total length of the flow passage is preferable 7-35 mm.sup.2, for example about 20 mm.sup.2. The inhaler may be adapted to be used only once, and the tubular body of the inhaler may be a length of a simple tube similar to a drinking straw.
