Title: Method and apparatus for detecting and announcing pin fraud on coin telephones that use battery reversal pulses to meter charges
Inventor: AKHTERUZZAMAN AKHTAR
IPC: H04M17/02
Filed: 1999-11-01
Granted: 2001-07-11
Abstract: Pin fraud of battery reversal pulse metered sophisticated coin telephones is detected, an announcement of the detected fraud made, and the fraud is stopped if the detected fraud continues by the method and apparatus of the invention. By carefully monitoring within the switch office the loop current that is flowing in the 48 volt battery circuit, especially in the more positive terminal portion of the 48 volt battery circuit, loss of current to a fraud ground at a remote coin telephone can be detected. Once a fraud ground is detected, an announcement is made to at least the calling station where the pin fraud was detected, which says in effect ""The pay telephone you are using is charging improperly for the service provided. If such improper charging continues the present call will be discontinued"". A convenient location in the switch office and an inexpensive component configuration make the addition of this pin fraud detection, announcement and prevention apparatus very cost effective.

Title: Method of depositing a copper seed layer which promotes improved feature surface coverage
Inventor: HASHIM IMRAN
IPC: C23C14/40
Filed: 1999-12-21
Granted: 2003-01-21
Abstract: We have discovered a method of improving step coverage of a copper seed layer deposited over a semiconductor feature surface which is particularly useful for small size features having a high aspect ratio. Using a contact via as an example of a high aspect ratio feature, we have demonstrated that despite previously-held views, it is possible to increase the copper seed layer coverage simultaneously at the bottom of the via and on the wall of the via by increasing the percentage of the depositing copper species which are ions. The percentage of species ionization which is necessary to obtain sufficient step coverage for the copper seed layer is a function of the aspect ratio of the feature. For features having a 0.25 μm or smaller feature size, an aspect ratio of about 3:1 requires that about 50% or more of the copper species be ions at the time of deposition on the substrate. As the aspect ratio increases to about 4:1, the percentage of species which are ions is preferably increased to between about 60% and 70%. When the aspect ratio is about 5:1 or greater, the percentage of species which are ions is preferably increased to greater than 80%. This increase in the percentage of copper species which are ionized can be achieved using techniques known in the art, such as, for example, laser ablation of the copper target, electron cyclotron resonance, hollow cathode, and applicants' preferred technique, an inductively coupled RF ion metal plasma. We have further discovered that when an inductively coupled plasma is used to increase ionization, an increase in power to the ionization source is not enough to obtain the desired percentage of ions in many case. It is also necessary to increase the plasma gas pressure. Typically the plasma gas is argon, and the argon pressure in the copper seed layer deposition chamber is increased to fall within the range of about 20 to about 100 mT, preferably between about 30 mT and 70 mT.

Inventor: ROLLINS WILLIAM
IPC: H04H20/67
Filed: 2000-02-19
Granted: 2002-10-21
Abstract: A system for aligning the phase characteristics of N identical digitized audio program signals distributed from a studio to N broadcasting stations via N nine division multiplex (TDM) communication signals includes N TDM multiplexers, each of which (i) multiplexes a digitized audio program signal into at least one channel of a TDM communication link established between the studio and one of the N broadcasting stations, and (ii) multiplexes a timing signal into another channel of the TDM communication signal. A TDM de-multiplexer at each of the broadcasting stations extracts the digitized audio program signal and the timing signal from the corresponding TDM communication signal. A timing signal comparator compares the extracted timing signal to a local timing signal that is delayed by a precise and adjustable amount, and produces an offset time corresponding to the comparison result. The delay adjust circuit dynamically adjusts the delay of the TDM signal as a function of the offset time, preferably so as to drive the offset time to substantially zero. The timing signal at the studio and the timing signals at each of the broadcast stations are provided by an existing time distribution network.
