Abstract: A PV array rail mounting system for use on support structures that include a substrate and covering material. In an aspect, the PV array rail mounting system is configured to be mounted to a roof with various tile types. In an aspect, the PV array rail mounting system includes a mounting hook for shared rails that allow the rails to be adjustably mounted. The overall PV array rail mounting system is configured to allow a rail be mounted on a roof tiles without the excessive removal of such tiles when mounted.

Abstract: A gearbox includes a planetary gearset and a first input shaft coupled to a sun gear of the planetary gearset. A second input shaft is coupled to a ring gear of the planetary gearset, and an output shaft is coupled to planet gears of the planetary gearset via a carrier. The gearbox further includes a second coupling path between the first input shaft and the second input shaft that is separate from the planetary gearset.

Abstract: An IC package includes an IC die mounted on a substrate that includes an ESD protection structure formed within the substrate to dissipate any charge accumulation associated with the package's no-connect pins resulting from human body model ESD and/or voltage spikes during package testing. For some embodiments, the ESD protection structure includes a resistive element formed in the substrate between the no-connect pin and a power plane. For other embodiments, the ESD protection structure includes a conductive ring formed in the substrate and laterally surrounding the land pad of the no-connect pin.

Abstract: A method and a pulse pressure sensor for sensing an arterial pulse pressure waveform. In one embodiment, the pulse pressure sensor includes a housing, a diaphragm, a piezoelectric device, and a self-contained amplifier. The skin-contact diaphragm is attached across a recess or opening in the housing. The piezoelectric device has a first portion mounted in a fixed relationship to the housing and a second portion displacementally coupled to the diaphragm. The solid-state amplifier has a signal input coupled to the piezoelectric device, wherein the piezoelectric device and amplifier together have a frequency response at least including a range from below approximately 0.1 hertz to above approximately 250 hertz. In one such embodiment, the housing and the skin-contact diaphragm of the sensor are stainless steel. In one such embodiment, the diaphragm has a skin-contact surface with a skin-contact dimension of between approximately 0.4 inch and 0.6 inch.
