Abstract
Abstract Disclosed is a touch-programmable lighting and security device in the form of a stand lamp which can be programmed to provide illumination by means of an AC bulb or DC bulb in conjunction with parameters including the ambient light level, presence of people, and AC mains power failure. In one embodiment, this novel lighting and security device includes a transmitter which transmits an Alarm signal to a remote receiver upon detection of an intruder. This user friendly device conveniently plugs into any wall power outlet by means of a suitable length of cable and it can be easily programmed by touching different nonmetallic areas of the device. In one embodiment, four indicator lights in the form of LEDs are provided to identify its prevailing mode.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
195 words
A control for electrically energizing an illumination means, said control having: input means for connection to a source of electrical energy, output means for connecting electrical energy from the control to said illumination means, a first means to detect the presence of moving infrared radiation sources, a second means to compare the level of ambient light with a preset threshold, and a third means to electronically override the said first means and said second means; said control having modes of operation which comprise: a first operation mode wherein said output means is energized upon the detection of a moving infrared radiation source and remains energized for a predetermined period of time after cessation of said detection, provided the ambient light intensity is below a predetermined level, a second operation mode wherein said output means is energized when the ambient light intensity is below a predetermined level regardless of detection of a moving infrared radiation source, and a third operation mode wherein said output means is energized regardless of detection of a moving infrared radiation source or ambient light level, wherein each of said operation modes is controlled by a signal generated by a proximity sensor.
Claim 2
Dependent Claim
195 words
A control for electrically energizing an illumination means, said control having: input means for connection to a source of electrical energy, output means for connecting electrical energy from the control to said illumination means, a first means to detect the presence of moving infrared radiation sources, a second means to compare the level of ambient light with a preset threshold, and a third means to electronically override the said first means and said second means; said control having modes of operation which comprise: a first operation mode wherein said output means is energized upon the detection of a moving infrared radiation source and remains energized for a predetermined period of time after cessation of said detection, provided the ambient light intensity is below a predetermined level, a second operation mode wherein said output means is energized when the ambient light intensity is below a predetermined level regardless of detection of a moving infrared radiation source, and a third operation mode wherein said output means is energized regardless of detection of a moving infrared radiation source or ambient light level, wherein each of said operation modes is controlled by a signal generated by a proximity sensor.
Claim 3
Dependent Claim
50 words
The control as claimed in claim 1, wherein the proximity sensor comprises a plurality of circuits each including an antenna for detecting an electrical signal induced onto it, an amplifier means for amplifying said electrical signal, and a pulse condition means for producing an electrical pulse from the amplifier means.
Claim 4
Dependent Claim
62 words
The control as claimed in claim 1 including: a first indicator means which is energized at each detection of a moving infrared energy source when functioning under said first operation mode, a second indicator means which is energized continuously when functioning under said second operation mode, and a third indicator means which is energized continuously when functioning under said third operation mode.
Claim 5
Dependent Claim
22 words
The control as claimed in claim 3, wherein each indicator means is adapted to give a visual indication of the operation mode.
Claim 6
Dependent Claim
40 words
The control as claimed in claim 1, further comprising means for transmitting an alarm signal and including a fourth operation mode wherein said alarm signal is transmitted to an alarm receiver means whenever said first means detects moving infrared radiation.
Claim 7
Dependent Claim
23 words
The control as claimed in claim 5, including a fourth indicator means which is energized continuously when functioning under said fourth operation mode.
Claim 8
Dependent Claim
22 words
The control as claimed in claim 5, including a fourth indicator means which flashes continuously when functioning under said fourth operation mode.
Claim 9
Dependent Claim
62 words
The control as claimed in claim 1, further comprising: means to prevent said output means from being de-energized as a result of feed-back of illumination from said illumination means, while functioning under said first and second operation mode; and means to de-energize said output means after the ambient light level rises above a predetermined level, while functioning under said second operation mode.
Claim 10
Dependent Claim
38 words
The control as claimed in claim 1, further comprising means for adjusting the duration for which said output means remains energized after cessation of detection of a moving infrared radiation source while functioning under said first operation mode.
Claim 11
Dependent Claim
25 words
The control as claimed in claim 1, further comprising means to automatically reset to a preferred operation mode after a total loss of electrical energy.
Claim 12
Dependent Claim
30 words
The control as claimed in claim 1, including an integral battery-operated back-up facility to automatically power the control in the event of disruption of alternating current power to the control.
Claim 13
Dependent Claim
62 words
The control as claimed in claim 1, including means to automatically connect a battery-operated reserve to the said control in the event of disruption of alternating current power to the said control and including an auxiliary illumination means adapted to be activated by said battery-operated reserve in accordance with the specific operation mode under which the control has been set to operate.
Claim 14
Dependent Claim
24 words
The control as claimed in claim 1, wherein the electronic, electrical and mechanical components of the control are housed in a self-contained portable unit.
