Title: Parallel off-hook detection for both line-available and phone pick-up detection
Inventor: KRAMER RICHARD ALAN
IPC: H04M1/71
Filed: 1994-03-25
Granted: 2004-02-10
Abstract: A secondary communications device, such as a modem, a facsimile machine, an automatic meter reader or an answering machine, shares a telephone line with a subscriber's telephone and must grant the telephone primary access to the line. The present invention prevents the secondary device from seizing the line when the telephone is already off-hook and will terminate a line seizure by the secondary device if the subscriber picks up the telephone handset during use of the line by the secondary device. An average interval for charging a capacitor to a threshold voltage in response to an on-hook voltage appearing across the telephone line is determined. When the secondary communications device is ready to use the line, circuitry measures an interval for charging the capacitor in response to the current voltage appearing across the telephone line. The secondary communication device seizes the line only if the measured interval does not exceed the average interval by more than a predetermined amount. After seizure by the secondary communication device, a steady-state condition is brought about between the secondary device, the line steady-state impedance, and the central office voltage source. If the line impedance drops from the steady-state value, the circuitry assumes that the subscriber has taken the telephone off-hook and terminates the line seizure by the secondary device.

Abstract: A high density ink jet printhead is fabricated by first  forming a  body  subassembly  comprising  a piezoelectric  main  block  having  metallic  layers disposed on opposite first and second sides thereof, and piezoelectric sheets secured to front portions of the metallic layers.  Using a precision dicing saw, a first spaced series of parallel grooves, longitudinally extending between the front and rear ends of the subassembly,  are  cut  into  the  first  side  of  the subassembly.  The subassembly is then placed, groove side down, in a support fixture having mirrors secured thereto and positioned adjacent the opposite ends of the grooves.  Reflections of opposite groove ends in the mirrors are then used as line-of-sight guides to position the saw which is then used to form a second series of grooves in the second subassembly side which are in precise lateral alignment with the first series of grooves.  Covering blocks are then secured to the opposite piezoelectric sheets over the open outer sides of  the  grooves  and  form  therewith  interior  ink receiving channels bounded along their  lengths by piezoelectrically deflectable side wall segments of the printhead body.   The rear ends of the channels are sealed off, ink supply conduits are communicated with rear end portions of the channels, and a plate member having first and second spaced series of ink discharge orifices respectively communicated with the front ends of the first and second series of interior channels is secured over the front end of the printhead body.
