A riding or travelling bit for horses comprising at least one rigid or articulated bit rod (2) made at least partially of metal. The inventive bit is characterized in that the bit rod has at least two different metal parts (4,6) thus creating a difference in electrical potential. This difference in electric potential creates a sour taste for the horse, encouraging it to chew and making it receptive to assistance from the reins. In one embodiment, one member (4) of the two-membered bit rod (2) is made of one type of metal and the other member is made of another type of metal. Both members are coupled together in a known manner by means of self-engaging eyelets (8, 10) in a chain-like fashion. However, at least one of the eyelets is lined (12) with electrically insulating material. In another embodiment, both metal surfaces are electrically connected to various poles of at least one commercial electric battery cell (94) which is accommodated in a tubular receptacle (92) forming one part of the bit rod (90).

A computer microphone with a dual power source capability is disclosed. This dual power source capability allows the microphone to receive power from an internal power source or an external power source disposed in computer hardware. In the event that the computer microphone is receiving power from the internal power source, and power is thereafter provided from the external source disposed in computer hardware, the present invention provides for the automatic turning off of the internal power source. In related fashion, in the event the computer microphone is receiving power from the external power source disposed in the computer hardware, and that external power source is thereafter turned off, the present invention automatically provides the computer microphone with power from the internal power source.
摘要:
A test device for detecting bilirubin in serum is provided which comprises a carrier and, incorporated therewith, a composition comprising a diazonium salt, p-toluenesulfonic acid and dyphylline. The test device is free of the undesirable characteristic of nonuniformity of color development when reacted with a test sample. Uniform color development provides a more accurate and reliable quantitation of serum bilirubin. A method of making and a method of using the device are likewise disclosed.
摘要:
A method of manufacturing a semiconductor package, where the package includes a surface for attachment of the package to a device by a joint formed of a connective material in a joint area of the surface. The method is characterized in that it comprises the step of patterning one or more channels on the surface which channels extend away from the joint area towards an edge of the surface. Also the method has the step of applying a compound to one or more channels which compound interacts with the connective material, such that when the semiconductor package is attached to the device the interaction defines one or more paths in the connective material. These correspond to the one or more channels on the surface and allow the passage of waste material away from the joint area to the outer edge of the surface.
摘要:
An integrated sensor chip unit and fabrication method includes a measured-value pickup for determining measurement data and a circuit arrangement for enabling a wireless power supply and interrogation of the measurement data. The measured-value pickup is formed as an integratable sensor, and the circuit arrangement is formed as an integrated semiconductor circuit module. The sensor and the semiconductor circuit module are mechanically and electrically conductively connected to one another using one or more microsystems engineering techniques.
摘要:
A golf swing training apparatus consisting of a base; a club guide ring; left, right, and rear hinge shafts; left, right, and rear hinge sleeves, the left, right, and rear hinge shafts extending through the left, right, and rear hinge sleeves so that the left and right ends of the left, right, and rear hinge shafts extend leftwardly and rightwardly from the left and right ends of the left, right, and rear hinge sleeves. Each of the left and right ends of the left, right, and rear hinge shafts are attached to the base or making up a part of the base. Left, right, and rear slip joints are provided for attaching the club guide ring to the left, right, and rear hinge sleeves. The rear slip joint consists of an alternately extendable and retractable shaft for, upon alternate extension and retraction, alternately pivoting and counter-pivoting the club guide ring about the left and right hinge shafts.
