A combination mixing pitcher having a mixer subassembly that incorporates an impeller which is reciprocally longitudinally slidably movable but not rotatable within the pitcher. The impeller is fixed to one end of a plunger rod that reciprocates slidably through a matingly engagable axial channel in a lid that peripherally closes the pitcher mouth. The impeller employs a plurality of flat, radially pitched, fan shaped blades that are in radially equally spaced relationship to each other and that extend between a central hub and a peripheral polygonally configured rim. The mixer subassembly maximizes mixing of a liquid in the pitcher with a minimum of time and energy and with no spillage.

A portable wound care kit sized, shaped, and configured to carry only articles necessary for wound care treatment. In one embodiment, the wound care kit contains only a container of wound treatment medicament and two or more wound coverings. However, the wound care kit may also be configured to carry wound cleansing wipes or wound wash. The wound care kit is configured to permit ready and easy access to the wound care treatment articles.

An integrated circuit die (10) includes a substrate (64), a plurality of metal interconnect layers (62) formed over the substrate (64), an insulating layer (58), a first pad (12), a second pad (14), and a probe pad (16). The first pad (12) is formed over the insulating layer (58) at an edge (11) of the integrated circuit die (10). The second pad (14) is formed over the insulating layer (58) adjacent to the first pad (12) on a side of the first pad (12) that is opposite to the edge (11). The probe pad (16) is formed over the insulating layer (58) on a side of the second pad (14) that is opposite to the edge (11), wherein the probe pad (16) is electrically connected to the first pad (12). The probe pad (16) may be formed over active circuitry of the substrate instead of over a peripheral area of the die (10), thus reducing the surface area of the die (10).

A technique for alleviating the problems of defects caused by stress applied to bond pads (32) includes, prior to actually making an integrated circuit (10), adding dummy metal lines (74, 76) to interconnect layers (18, 22, 26) to increase the metal density of the interconnect layers. These problems are more likely when the interlayer dielectrics (16, 20, 24) between the interconnect layers are of a low-k material. A critical area or force area (64) around and under each bond pad defines an area in which a defect may occur due to a contact made to that bond pad. Any interconnect layer in such a critical area that has a metal density below a certain percentage can be the cause of a defect in the interconnect layers. Any interconnect layer that has a metal density below that percentage in the critical area has dummy metal lines added to it.

A bond pad (200) has a first wire bond region (202) and a second wire bond region (204). In one embodiment, the first wire bond region (202) extends over a passivation layer (18). In an alternate embodiment, a bond pad (300) has a probe region (302), a first wire bond region (304), and a second wire bond region (306). In one embodiment, the probe region (302) and the wire bond region (304) extend over a passivation layer (18). The bond pads may have any number of wire bond and probe regions and in any configuration. The ability for the bond pads to have multiple wire bond regions allows for multiple wire connections to a single bond pad, such as in multi-chip packages. The ability for the bond pads to extend over the passivation layer also allows for reduced integrated circuit die area.
摘要:
A system and method for converting onboard battery-powered, free-flight drones into ground-powered tethered drones that overcome the impediments designed into safeguarded free-flight drones. In combination with a ground-sourced power supply for the drone, power being delivered to the drone through a tether, the system comprises a battery emulating module that provides false signals to the drone's battery circuit board such that the onboard batteries may be removed and the alternative ground-based power source utilized without causing the drone's main circuit board to initiate a systems shutdown.

A drone system includes a drone that includes a propulsion system, a flight stabilizer system, and an air payload interface unit, and a camera system, wherein the camera system includes a camera stabilizing unit, and a ground support system to which the drone is detachably coupled through a tether unit, and for providing electrical power to the propulsion system. The drone system further includes a ground payload interface unit for receiving and transmitting command and telemetry information to the air payload interface unit through the tether unit, and a controlling device for controlling the propulsion system and the camera system through the tether unit.
摘要:
A method provides an interconnect structure having enhanced structural support when underlying functional metal layers are insulated with a low modulus dielectric. A first metal layer having a plurality of openings overlies the substrate. A first electrically insulating layer overlies the first metal layer. A second metal layer overlies the first electrically insulating layer, the second metal layer having a plurality of openings. An interconnect pad that defines an interconnect pad area overlies the second metal layer. At least a certain amount of the openings in the two metal layers are aligned to improve structural strength of the interconnect structure. The amount of alignment may differ depending upon the application and materials used. A bond wire connection or conductive bump may be used with the interconnect structure.
