摘要:
One-part implant for attachment of artificial teeth comprising an anchoring part and a mounting part, wherein the anchoring part and the mounting part are configured in one piece. The anchoring part of the one-part implant has a bone contact surface B and a soft tissue contact surface S. The soft tissue contact surface S is at least partially hydroxylated or silanated, which results in an improved soft tissue integration.

Solar powered outdoor lighting and/or alarm systems are provided and include a light source or alarm, a passive infrared (PIR) sensor in conjunction with a battery recharged via solar cells, and a control circuit coupled to the light source or alarm, the PIR sensor, and the rechargeable battery. The control circuit guarantees that the light source or alarm is turned on by the battery only when the sensor senses the presence of a moving target. The systems may include a light detector which is utilized to prevent the system from activating in daylight. In the case of a lighting system, a timer is utilized to turn off a lamp after a desired period of time (e.g. 3 minutes). By limiting the "on-time" of the light source, a two to five watt bulb may be used. In the case of an alarm, the alarm may be hardwired to the control circuit; or if desired, a transmitter powered by the rechargeable battery may be used to transmit an alarm signal to a remote receiver. The receiver is in turn coupled to its own power supply and to a control circuit which controls or switches desired components such as horns, bells, lights, etc.

A simple optical system collects and applies radiation from a predetermined field of view onto a thermopile detector. The thermopile detector has a plurality of rows of thermocouples having all active junctions with alternate polarity which are aligned in columns of the same polarity, whereby in response to an object moving across the thermopile an output signal is produced of alternately changing polarity. Logic circuitry is provided for processing the signals from the thermopile in a predetermined polarity sequence to discriminate against false alarms and for indicating the presence of an intruder and sounding an alarm.

A integrated IR detector for detecting both motion and fire/smoke includes in one embodiment a single source of IR radiation and separate IR sensors for sensing motion and smoke. The separate sensors are coupled by their outputs to separate amplifier circuits and provide separate outputs indicating motion (intrusion) detection and smoke detection. The entire arrangement of IR source and dual sensors are mounted in a single housing and powered by a common power supply. In a second embodiment, a single passive IR motion detector having a pair of phase opposed series connected sensors is coupled to a circuit for detecting motion (intrusion) while one of the pair of sensors is coupled to a circuit for sensing changes in ambient temperature. The circuit for detecting ambient temperature changes includes logic analysis and time constant filtering to produce an alarm signal only when ambient temperature changes exceed a preset threshold rate of degrees per second. Common power supplies and control units are disclosed which allow coupling alarm signals on a single two-wire or four-wire circuit.
