Filed: 1995-07-03
Abstract: On a découvert que le niveau de phosphorylation de la protéine DP-1, d'une partie du complexe du facteur de transcription DP-1/E2F1 ainsi que celui des protéines DP-2 et DP-3, était régulé au cours de la progression du cycle cellulaire. Cette découverte permet de fonder les dosages sur des modifications de la phosphorylation des protéines DP, notamment pour des agents pouvant affecter l'état de phosphorylation de DP. On a remarqué que DP-1 présente une affinité plus forte pour l'ADN lorsqu'elle se trouve dans un état hypophosphorylé. On décrit également des anticorps qui reconnaissent les sites de phosphorylation sur DP-1.

Patent CA-2196010-A1 (CA)
Title: Adaptive iir multitone detector
Inventor: MAY CARL JEROME
IPC: G01H17/00
Filed: 1997-01-27
Abstract: An adaptive Infinite Impulse Response (IIR) filter is provided that can adaptively detect the presence of one or more tones in its input stream. The tones to be detected may be of arbitrary frequency, subject only to a limitation that such tones fall within a frequency band consistent with accepted sampling principles (e.g., a maximum frequency of interest no greater than one-half the sampling frequency -Nyquist sampling criteria). An IIR filter developed according to the method of the invention will adaptively locate the frequencies of tones to be detected, thereby allowing for frequency drift from nominal expected frequency values with no loss in accuracy. Such a filter will also process the input signal sample-by-sample, thereby avoiding the blocking problem of FFT-based filter approaches. With the filter of the invention, an application can identify the frequencies, associated power levels, SNR and duration of the tones. Thus, such an application can use a simple user specified library of tone parameters to decide if tones of interest are present in the input stream.

Abstract: The present invention relates to a thermo-volumetric motor (10) comprising a continuous incompressible fluid path in the form of a hydraulic oil path (12), a continuous compressible fluid path in the form of a refrigerant path (14), and a solar collector (18). The solar collector (18) is adapted to absorb heat from a heat source, in this example, sunlight. The hydraulic oil path (12) includes pressure transfer means, in this example a pair of hydraulic cylinders (20A, 20B) located in a parallel flow arrangement. The oil path (12) further comprises actuating means, in this example a hydraulic loader (22), in fluid communication with a first heat exchanger (24). The refrigerant path (14) comprises a pump (28) operatively coupled to the hydraulic motor (22), and heat transfer means, in this example a second heat exchanger (25). The refrigerant path (14) further comprises cooling means, in this exampla a first accumulator or condenser (32) used for cooling the refrigerant. The second heat exchanger (25) comprises a shell and tube arrangement wherein refrigerant is passed through a helical tube, and a first phase change substance, such as sodium acetate trihydrate, is contained within the shell. In operation, sunlight absorbed by the solar collector (18) is used to fuse the first phase change substance and thereafter refrigerant passing through the second heat exchanger (25) cools and solidifies the first phase change substance releasing latent heat. The refrigerant then expands and is ejected into one of the hydraulic cylinders (20A, 20B) thus effecting movement of a piston (36A, 36B).  The piston (36A, 36B) drives hydraulic oil through the hydraulic oil path (12) and drives the hydraulic motor (22) which can be used to provide motive power.

Title: High-speed data transmission in mobile communication networks
Inventor: R S NEN JUHA
IPC: H04W92/18
Filed: 1996-03-06
Abstract: The invention relates to a digital mobile system and a method for high-speed data transmission in a digital mobile system. The mobile network allocates n parallel rate-adapted traffic channels to a high-speed user data signal which requires a data transfer rate R user within a range (n-1)*R ch<R user<n*R ch, wherein R ch is the maximum transmission rate of a single traffic channel. The user data signal is divided in the transmitter into transmission frames (L, L+1, L+2) for transmission via the parallel traffic channels (ch1-chn) in such a way that all the information bits in the transmission frames of n-1 traffic channels carry user data bits (DATA), and the user data transfer rate of each of the n-1 traffic channels is R ch. In the frames of the nth traffic channel (chn) the number of the information bits carrying user data bits (DATA) is selected to correspond to the user data rate R user-(n-1)*R ch exceeding the capacity of the other n-1 traffic channels.  The remaining information bits in the frames of the nth traffic channel carry stuff bits (FILL).

IPC: A61M16/10
Filed: 1997-07-30
Abstract: A system for continuing the monitoring of certain gases delivered to a patient during the administration of nitric oxide to provide therapy to the patient.  The nitric oxide is controlled by a electrically operated valve that is operated by means of an electrical signal from a CPU.  At times when the various gas monitors are being calibrated, the normal alarms based upon those gas monitors are conventionally disabled during that calibration time.  With thepresent invention, the electrical signal to the electrically operated valve is detected at the time the system goes into a calibration cycle and that detected electrical signal is used to establish limits such as a upper limit and a lower limit.  Therefore, when the electrical signal to the valve is thereafter monitored and its value exceeds either of those limits, the overall nitric oxide delivery system will activate an alarm to alert the user of an abnormal condition.  Thus an alarm system is present even when the various gas monitors are otherwise taken out of the system during their calibration.
