Abstract: A variable optical axis type bottle inspecting 
apparatus is disclosed. The bottle inspecting apparatus 
comprises illuminating means (10) for illuminating a bottle (12) 
continuously conveyed on rotation, an optical system for 
forming an image of lights transmitted through the 
bottle, photoelectric converting means for 
photoelectrically converting the transmitted light image 
of the bottle, optical axis changing means (14) for changing 
the optical axis of the optical system with respect to 
the photoelectric converting means (16) so that the 
transmitted light image of the bottle continuously 
conveyed is formed consecutively on the photoelectric 
converting means, and inspecting means for inspecting 
the sidewall of the bottle for defects, based on the 
transmitted light images photoelectrically converted by

Title: Oscillator with transient frequency response compensation
IPC: H03L3/00
Filed: 1989-10-20
Abstract: An oscillator circuit comprises an oscillator 10, a 
modulator 11, a temperature compensation circuit 12 and a 
transient compensation circuit 13. The modulator 11 is provided 
with a further control input I₃ coupled to receive a control 
signal V TC  provided by the transient compensation 
circuit 13. The control signal V TC  is effective to compensate 
the transient frequency response of the oscillator 10 by having 
a variation, as a function of time, which causes an offset in 
the frequency response of the oscillator 10 which is 
substantially the inverse of the transient response it is 
intended to compensate. The signal V TC  enables the frequency 
output of the oscillator 10 to stabilise rapidly within preset 
time limits, making the oscillator circuit particuarly suitable 
for transceivers having intermittent operation.

Patent EP-0388215-A3 (EP)
IPC: G10K11/34
Filed: 1990-03-15
Abstract: An ultrasound system (100) for investigating a subject (91) 
comprises a probe (102), a signal processing module (104), and an 
interconnecting cable (106). The probe includes an annular phased 
array transducer (120) defining multiple signal processing channels 
Ch1-CH12. The signal processing module includes a controller (106), 
a transmitter (110), a receiver (112), delay circuitry (114), and a video 
section (116). Within the delay circuitry, each signal processing 
channel includes an inphase branch and a quadrature branch. Each 
branch includes an analog-to digital converter (ADC 412, 422) and a 
delay first-in-first-out (FIFO 416, 426) memory. Dynamically variable 
delays are implemented by varying the sampling and FIFO input 
rates relative to constant FIFO output rates. The variable clock rates 
are derived by switching between phase-staggered replicas of a 
master clock MCLK, which has a rate at the nominal center 
frequency of the ultrasound signal prior to sampling. The timing 
circuit (700) used to derive the variable clock rate signal uses a focus 
FIFO (706) to serve as a timing buffer between the variable clock rate 
signal and the master clock signal. Inphase data streams from each 
channel are combined in a pipelined adder (314); quadrature data 
streams are similarly combined. An interpolator (318) permits 
accurate combinations of the summed inphase and quadrature data 
streams. The resulting combination is directed to the video section 
for output. Advantages of the disclosed system include low signal 
processing, memory and data rate requirements, resulting in a more 
reliable and economical high-performance ultrasound system.
