摘要:
A method and structure for coupling a semiconductor substrate (e.g., a semiconductor chip) to an organic substrate (e.g., a chip carrier). The coupling interfaces a solder member (e.g., a solder ball) to both a conductive pad on the semiconductor substrate and a conductive pad on the organic substrate. Thermal strains on the solder member during thermal cycling may be reduced by having a surface area of the pad on the semiconductor substrate exceed a surface area of the pad on the organic substrate. Thermal strains on the solder member during thermal cycling may also be reduced by having a distance from a centerline of the solder member to a closest lateral edge of the semiconductor substrate exceed about 0.25 mm.
摘要:
Magnetic nanoparticles and methods for their use in detecting biological molecules are disclosed. The magnetic nanoparticles can be attached to nucleic acid molecules, which are then captured by a complementary sequence attached to a detector, such as a spin valve detector or a magnetic tunnel junction detector. The detection of the bound magnetic nanoparticle can be achieved with high specificity and sensitivity.

A radiation detection system has a linear array of radiation detectors, which are preferably ionization chambers. The detectors are connected, preferably permanently, to a multi-channel signal processor through a flexible multi-conductor shielded cable. The multi-channel signal processor is connected to a controller, such as a personal computer, through a multi-conductor cable and a communication interface device. Multiple detector arrays and multi-channel electrometers may be connected to a single personal computer and used simultaneously.
摘要:
An occluding device for occluding fluid flow through a lumen of a body vessel. The device comprises a coil and fibers attached to the coil. The coil has about 5 to 60 grams of initial tension to facilitate the coil to fold when deployed. The fibers extend from the coil at a length.

A Micro Maple Spout and Method of Use made of rigid bacteria resistant materials that is significantly smaller than the current industry standard. The small size and nature of the construction materials of the Micro Maple Spout allows the collection tubing to be slid on and off instead of being permanently attached. The concomitant smaller tap hole in the sap trees results in far less sap tree damage than current designs and further results in significantly increased production of maple sap. One embodiment of the invention allows the use of smaller and less expensive collection tubing than the current industry standard and in yet another embodiment the Micro Maple Spout may be retro-fitted to existing prior art spouts.
摘要翻译:微型枫叶喷嘴和使用方法由刚性抗菌材料制成,明显小于目前的行业标准。 Micro Maple Spout的建筑材料的小尺寸和性质允许收集管滑动开和关,而不是永久地附着。 树汁中伴随的较小的孔洞导致比现有设计少得多的树莓伤害,并进一步导致枫树汁的生产显着增加。 本发明的一个实施例允许使用比当前行业标准更小且更便宜的收集管,并且在另一个实施例中,微枫叶喷嘴可以改装成现有的现有技术喷口。
摘要:
A handlebar adapted to be fitted onto the handles of a wheelchair having two substantially parallel handles, together with an improved push-button mechanism for locking the handlebar securely into position. The handlebar is designed with multiple ergonomically correct gripping stations which reduce strain on the hands, wrists and forearms of a person using the handlebar. Methods of retrofitting existing wheelchairs, as well as tools used in performing the retrofitting operation, are also provided.
摘要:
An earth working apparatus comprising a wheeled vehicle capable of traversing the ground and a ground breaking assembly mounted on the front end of such vehicle, such ground breaking assembly comprising a cylinder mounted for movement with the vehicle and for rotation about its cylinder axis, such cylinder having teeth projecting from its cylinder surface; the ground breaking assembly also having a shield partially surrounding the cylinder and provided on its inner surface close to the cylinder with fracture boards against which large pieces of pavement, frozen earth or stone impact, thereby causing such large pieces to fragment.
摘要:
A violation enforcement system configured to impair the view of a driver through a windshield of a vehicle is provided. The violation enforcement system includes a plurality of covering assemblies. Each of the covering assemblies has one or more suction assemblies configured for placement against a windshield of a vehicle. A pump assembly is configured for pneumatic communication with the one or more suction assemblies. The pump assembly is configured to develop a partial vacuum between the suction assemblies and the windshield. A release assembly is configured for pneumatic communication with the one or more suction assemblies. The release assembly is further configured to actuate release of the suction assemblies from the windshield. A GSM module is configured to receive information from GPS satellites and then calculate the geographical position of the violation enforcement system.
摘要:
Method and system for automatically adjusting a formula for producing a food product from a plurality of ingredients includes at least one sensor that measures a property of an ingredient used in the formula or an ambient condition around equipment producing the food product. A processor determines an adjusted quantity of at least one ingredient used in the formula based on the measurement by the sensor(s) and a quantity of that ingredient set forth in the formula. The adjusted quantity of this ingredient is mixed together with remaining ingredients in the formula. The sensor may be a sensor that measures temperature of the at least one ingredient, a sensor that measures moisture content of the at least one ingredient, a sensor that measures ambient temperature around the equipment, or a sensor that measures relative humidity around the equipment.
