Title: Mca assay/kit for detecting metal cations
Inventor: CARLSON RANDALL A
IPC: C07K16/44
Filed: 1994-06-02
Abstract: The invention provides method and kits for detecting a metallic cation in a sample of a body fluid. The preferred method and kits include the use of at least two different types of antibodies having different specificities. In the preferred method, the sample of body fluid can be contacted with an effective amount of a capture antibody specific for a naturally occurring polypeptide that can bind the metallic cation to form a first antigen-antibody complex. An effective amount of an antibody specific for an epitope on a metallic cation-naturally occurring polypeptide complex or an antibody specific for a metallic cation is added to the first antigen-antibody complex to form a second antigen-antibody complex. The amount of the metallic cation in the sample of body fluid is determined by detecting the amount of the second antigen-antibody complex.

A number of different criteria can be employed in determining  if a  satellite can be  assigned   a  new communication  link,   including:   determining  if  the associated  satellite  has  already  been    assigned  a predetermined maximum number of communication links; and determining if the associated satellite, or a particular beam, is transmitting at or near to a power level that corresponds to a maximum peak flux density at the surface of the earth. Each of the steps of assigning is preferably accomplished  such  that  the  communication  link  is simultaneously established through at least two of the satellites to provide for diversity reception at a user's terminal (13).

Abstract: This invention relates to a wild bird feeder which includes replaceable feeding perches.  The device is comprised of a hollow molded plastic base which con-tains the feeding solution.  Contained in the base are a supply opening and a number of feeding station openings. Each of the feeding station openings has a perforated punch-out ring surrounding it, which can be removed by the owner to reconfigure the base for use with other birds.  With the punch-out ring in place, the feeding station openings in the base are used to engage a first type of feeding perch.  With the punch-out ring removed, the expanded feeding station openings are now of a size to engage a second type of feeding perch.  Both types of feeding perches are a single, molded structure consisting of a joined attracting head and a perch leg configured according to the type of bird to be fed.  The punch-put rings allow the owner to choose which type of bird he wants to feed and construct the feeder accordingly by choosing the appropriate perch.

IPC: G01V1/153
Filed: 1996-10-15
Abstract: Seismic exploration for hydrocarbons may use an eccentric-mass (or "swinging-weight") vibrator as the seismic source. According to the invention, a vibrator undergoes alternate periods of acceleration and deceleration, during one of which the vibration may be annulled. For example, the rotating mass may be formed in a plurality of parts; then the several parts are disposed in a manner that rapidly and automatically balances their vibratory forces during the period when the vibration is to be annulled, and that adds their vibratory forces during the other period.The invention further provides for modulation of the frequency-time relation during deceleration, for synchronization of several vibrators, and for modulation of the effective output force by controllable variation of the mass, eccentric radius or relative phase of the several parts of the rotating mass; in such modulation, only resultant forces are applied to the vibrator bearings.

Abstract: A fractional - N frequency synthesizer comprises a voltage-controlled oscillator (107) for generating an output signal (Fo) in response to a control voltage derived by a digital-to-analog converter (105) from a digital error signal (e). The error signal is derived by a differencing device (103) which subtracts a digital signal (Do) representing the actuated frequency of the output signal from an input signal (Fd) having the desired frequency for the output signal. The digital signal representing the output signal frequency is derived by a frequency discrimination device (101) which determines the instant frequency of the analog output signal and provides a corresponding digital representation with zero static frequency error. In preferred embodiments, the frequency discrimination device is a delta-sigma frequency synthesizer in combination with a decimator (102). This frequency synthesizer configuration avoids deficiencies due to non-linearity and noise sensitivity of analog phase detectors. The invention also provides a frequency discriminator (101') comprising a feedforward path including a multimodulus divider (201) for dividing the frequency of a digital signal (Fo) in dependence upon a division ratio control signal, comparison (202) for comparing the divided frequency signal with a reference frequency signal (Fref) to provide an error signal, and a feedback path comprising a circuit having a transfer function of 2-Z-1 and responsive to the error signal and the reference frequency signal to provide the division ratio control signal.
