Abstract: A concrete vibrator head includes an elongated body having a front end and a back end. The back end of the vibrator head is attached to a rotating shaft which causes the vibrator head to vibrate at a desired vibration frequency. The elongated body is tapered from the front end to approximately halfway towards the back end. This taper may be defined by a continuous straight line slope of the outer surface of the elongated body, or a stepped slope formed from a series of interconnected cylindrical portions of the elongated body which increase in diameter from the front end to approximately midway on the elongated body of the vibrator head.

Title: Methods and devices for xerogel based sensors
Inventor: CHODAVARAPU VAMSY
IPC: G01N21/76
Filed: 2013-09-18
Abstract: Chemical sensors today are deployed in massive volumes across multiple industries and yet at the same time they are subject to substantial research and development effort to establish new, faster, lower cost, more accurate, more sensitive chemical sensors. Such sensors and sensor arrays are being exploited across chemistry, biology, clinical biology, environmental science in civilian and military markets. Amongst the many sensor methodologies are xerogel substrates with two moieties, a receptor for molecular recognition of the analyte and a luminophore for signaling the recognition event. In order to fulfill the requirements for low cost there is a requirement for electronic excitation / read circuits that can support architectures with optical source ¨ N sensors ¨ X filters ¨ M detectors, where M >= N and X = N¦M . According to embodiments of the invention electronic excitation /  read circuits for phase based luminophore sensors are presented that are compatible with single CMOS  chip implementation and monolithic integration of the optical excitation /  detection elements.

Abstract: Embodiments provide an apparatus for providing a nonlabor-intensive process for sealing an opening formed in the ground with a chemically-inflatable bag. The chemically-inflatable bag comprises two or more chemical reactants, one of which is a liquid reactant that is initially stored in a liquid-containing device. The liquid-containing device has a removable cap, which upon removal or breakage of the cap permits the liquid reacting agent to contact and react with another reacting agent. The chemical reaction produces carbon dioxide, which expands the chemically-inflatable bag from a collapsed condition to an inflated condition. In the inflated condition, the chemically-inflatable bag fills and protects the integrity of the formed cavity.
