A force sensor system for use in monitoring weight bearing on a location. The force sensor system comprises at least one a foot force sensor, a palm force sensor, and a knee force sensor. The foot force sensor comprises a flexible insole containing a plurality of inflatable pockets that are inflated with air or liquid. The palm force sensor and knee force sensor each comprise a wrap to be worn around the palm and knee, respectively. Each wrap comprises a pocket. Each pocket is connected to a tube that, in turn, connects with a pressure sensor and a connector coupling that is remote from the pocket. Each coupling contains a valve. The valve opens to allow inflation and deflation of each inflatable pocket. The pressure sensors measure the air or liquid pressure within each of the inflatable pockets, and convert the corresponding pressure signal into a suitable output signal medium, usually electrical signals. The output signal from the sensors provides accurate real time input data to a weight bearing biofeedback system or to control a stimulator for activation of an electronic orthosis to normalize dynamic gait patterns.

Methods for indicating whether a crankcase of an engine is breeched are provided. One example method comprises restricting a communication of the crankcase with atmosphere, acting to increase or decrease a crankcase pressure, and indicating whether the crankcase is breeched based on the crankcase pressure. Another example method comprises sensing a crankcase pressure component, and indicating whether the crankcase is breeched based on the crankcase pressure component, the crankcase communicating with atmosphere via a conduit, a restrictedness of the conduit responsive to one or more of a crankcase pressure and a signal from an electronic control unit of the motor vehicle. Still other examples provide more particular methods for indicating whether the crankcase is breeched, and example configurations that enable the various methods.

A scalable process transmitter architecture includes a unitized sensor module and an optional scalable transmitter. The sensor module has a sensor output that is configurable which can connect locally to a scalable transmitter module to form a transmitter, or can be wired directly to a remote receiver. The scalable transmitter can mount on the unitized sensor module and generates a scalable output for a remote receiver. The transmitter module can provide more advanced features for specific applications.

The second transmitting antenna is spaced from and connected to the second receiving antenna by a second bridging segment. The first antenna pair and the second antenna pair are placed in spaced connection by a first spacing segment and a second spacing segment so that an open area is defined by the first antenna pair, the second antenna pair, the first spacing segment and the second spacing segment.

A volumetric lubricant dispensing apparatus for delivering a precise volume of lubricant, such as oil, to a rotating machine element. The delivery mechanism includes a piston and cylinder assembly. A plurality of sensors are utilized to record operating conditions of the machine, element, environment, and lubricant. The apparatus is controlled either manually or with the aid of a controller unit such as a microprocessor. The output from each sensor is inputted into the microprocessor wherein an algorithm computes an responsive output. The responsive output is sent to the piston and cylinder assembly, which maintains an optimum lubricant condition within the reservoir wherein a rotating machine element located. Alternatively, for the purpose of qualitative control, the present invention may be described as a system intended for controlling lubricants, both mineral (natural) and synthetic based by measuring the condition characteristics of the lubricant. Some condition characteristics may include water or moisture content (the content could be any liquid, e.g., solvents like ketones are known to change condition characteristics like viscosity) and viscosity. Viscosity is related to temperature, therefore, temperature correlation to viscosity is helpful to provide relative indications for condition characteristics like lubricant flow.

A watercraft engine includes a lubrication system alarm control system which initiates an alarm when lubricant pressure within the lubrication system falls below an acceptable pressure. The alarm system compares lubricant pressure during engine operation with a lower pressure threshold which is determined as a function of engine speed. Thus, partial reductions in lubricant pressure are identified. Additionally, the alarm control system may be configured to emit an alarm if lubricant pressure fluctuates at a rate that is greater than a predetermined pressure fluctuation rate threshold.

An exhaust gas purification device of a diesel engine having a DPF (diesel particulate filter) for collecting particulate matters such as soot and unburned components from exhaust gas of the diesel engine calculates an oil dilution quantity as a quantity of fuel diluting engine oil from a regeneration time of the DPF and an operation state. The exhaust gas purification device alleviates an increase in the oil dilution quantity by using a regeneration device that causes the oil dilution quantity less than the oil dilution quantity caused by another regeneration device when the oil dilution quantity exceeds a predetermined value. Thus, both of suppression of the oil dilution quantity and inhibition of deterioration of fuel consumption due to post-injection can be achieved.

A pressure sensor and pressure-sensing catheter in which a deformable pressure sensing membrane is separated from an inner metalized surface on a rigid support by an air gap. An input allows a voltage to be applied to an electrode on the sensing membrane and an output allows reading of the signal modulation from the support surface. An outer sleeve overlays the membrane and a wire bus transmits the signals to a terminal connector. The catheter may include a vented air gap, a multiplexing wire bus, and an internal cable to maintain tension.

The present invention is directed to lubrication system having a reservoir having a body. A follower is moveably disposed in the body. The system further comprises an alarm system having an electrical switch operably associated with the follower. The alarm generates a signal when the follower is at a predetermined location in the body.

The alarm system may also generate a signal when the follower is at an upper location in the body such as when the reservoir is filled with lubricant wherein the signal acts to automatically interrupt the fill of lubricant.
