Inter-frequency handoffs in a CDMA or other wireless communication system are controlled using a noise-limited coverage trigger metric which is able to distinguish between same-frequency cell boundaries and other-frequency cell boundaries in the system. The trigger metric may be generated as a function of an average signal-to-noise measure for pilot signals received at a mobile station of the system and a linear sum of the signal-to-noise measures. The signal-to-noise measures may be generated in the mobile station and included in messages transmitted from the mobile station to one or more base stations of the system. The trigger metric is used to control a handoff from a current frequency to a new frequency in an ongoing call. The trigger metric may alternatively be based on a measure of mobile receive power alone. Other aspects of the invention reduce unnecessary searching for a new frequency and decrease the likelihood of âping-pongingâ from a current frequency to a new frequency by providing additional checks in the handoff process.

A method and system that minimizes pilot signal overlap and radio frequency ("RF") interference by estimating changes in pilot coverage for different traffic channel loading and power conditions. Once base stations are positioned, a terminal for measuring received pilot signal strengths, such as a mobile station or pilot scanner, is used to collect and generate the baseline pilot survey data, which is then stored on a disk or tape. Base station transmit pilot E. sub. C /I. sub. O s, i. e. , traffic channel loads on forward links, are also stored on disk or tape. The invention uses two adjustment factors associated with transmit power and traffic channel loading to optimize for different RF conditions, specifically for different base station transmit power or forward link loading conditions. For each RF condition, the methodology calculates the changes in the baseline pilot survey data. This reflects what E. sub. C /I. sub.

The present invention is directed to an assembly used for modifying an ordinary acoustic stethoscope to an electronically amplified stethoscope. This assembly is mechanically married to a conventional stethoscope's tubular structure. An earpiece unit which replaces the standard earpiece on the earpiece-end of the ordinary acoustic stethoscope, is positioned so the standard air column response of any ordinary acoustic stethoscope is picked up by a microphone placed inside this special earpiece unit, thus capturing the acoustic output of the parent stethoscope and transmitting it back to a preamplifier/amplifier and frequency equalizer unit (graphic equalizer). The electronic signal is then directed to a speaker located in the special earpiece unit for monitoring by the operator, or alternatively, such signal is directed to a number of other remote units for the purpose of facilitating teaching and learning.
