  • Patent number: 8923523
    Abstract: The selective filtering earplugs allow a user to filter most external and environmental sounds, only allowing a set of pre-approved sounds to be heard by the user. The earplugs include a sound acquisition module and at least one filtering earplug. The sound acquisition module includes a microphone for receiving environmental sounds and a controller for converting the received environmental sounds to a digital signal. First memory is provided for storing the digital signal and second memory is provided for storing a database of pre-approved sound signals. The controller compares the digital signal with the database of pre-authorized sound signals. If the digital signal matches a pre-authorized sound signal of the database, then a transmitter transmits the digital signal. The filtering earplug includes a receiver for receiving the digital signal and a converter for converting the digital signal into an audio signal.

  • Patent number: 8779893
    Abstract: The system for controlling vehicle ignition provides three separate levels of access to prevent unauthorized users from actuating ignition of a vehicle. The system includes a radio frequency identification tag having permanent computer readable memory and volatile computer readable memory associated therewith. The radio frequency identification tag is preferably embedded within a vehicle key. A predetermined permanently assigned authentication code is stored in the permanent computer readable memory and a variable time stamp is stored in the volatile computer readable memory. The permanently assigned authentication code and the variable time stamp are transmitted upon activation of the radio frequency identification tag. Vehicle ignition occurs only upon the mechanical operation of the key in a conventional ignition switch and matching of both the permanently assigned authentication code and the variable time stamp with codes and stamps stored in vehicle memory.

  • Patent number: 8776917
    Abstract: The stair-climbing apparatus has a series of articulating wheel sets extending below the platform. All of the wheel sets are vertically adjustable to negotiate stairways and similar changes of elevation. The lead wheel set is fixed longitudinally relative to the platform, while following wheel sets are longitudinally adjustable to adjust for the pitch or slope of different stairways. The apparatus uses sensors (e.g., mechanical, infrared, ultrasonic, etc.) to detect the presence of the stair risers and their height, control of the assembly being accomplished by a control circuit on board the machine. The wheel sets are raised and lowered independently of one another by pantograph mechanisms extending between the platform and the wheel sets. The horizontally adjustable wheel sets are positioned by a longitudinally disposed rack on the platform.

  • Patent number: 8596134
    Abstract: The bolt tension monitoring system provides remote monitoring of the tension of a bolt, thus allowing for remote monitoring of general structural health and integrity of the fastener. The bolt tension monitoring system includes a housing adapted for being retained on a head of a bolt to be monitored. The system further includes a force transducer positioned between the head of the bolt and a surface in which the bolt is fastened and measures tension between the head of the bolt and the workpiece surface. A controller circuit within the housing calculates the difference between currently measured tension between the head of the bolt and the workpiece surface and an initially measured tension. A wireless transponder mounted in the housing transmits an alert signal if the calculated difference exceeds a pre-defined threshold value.

  • Patent number: 8544646
    Abstract: The medical safety box is a system using RFID (Radio Frequency Identification) technology to ensure that correct delivery of the correct treatment in the form of medication or injection to in-hospital patients is consistently carried out. The system includes a medical box containing whatever medication or injection that needs to be administered to a specific patient. The box has a locking mechanism that can only be opened by an RFID wristband, which is worn by that same specific patient, thus assuring that the medicine in the box is administered to the correct patient.

  • Patent number: 8540468
    Abstract: The smart lid for smart bolts and probes is an electronic sensor for use with a smart bolt or probe having a color indicator for indicating tension. The smart lid includes a color sensor that provides electrical data corresponding to light received from the color indicator of the smart bolt or probe, a microcontroller that receives electrical data from the color sensor and converts that data to a digital form and compares the data against at least one limit, and provides a digital indication wirelessly to a remote monitor if the at least one limit has been exceeded. In this fashion a warning or emergency condition can be indicated when the tension experienced by the smart bolt is too low or too high. The smart lid may include an electrical power source that scavenges electrical power from ambient electromagnetic fields (EMF) and stores the electrical power in a battery.

  • Patent number: 8217783
    Abstract: A method of conserving energy and natural resources transported in subsurface pipelines and preventing environmental contamination therefrom by identifying the subsurface location of leaks of oil, gas, water or other natural resources transported in these pipelines includes adhering a continuous tape having a plurality of uniquely identified radio frequency identification (RFID) tags mounted thereon axially along the pipeline and use of a mobile robotic device to identify the specific location of a leak in the pipeline, thereby preventing loss of energy and water traveling through pipeline, contamination of these fluids and environmental contamination, and the use of additional fuel to replenish these lost natural resources.

  • Patent number: 8151025
    Abstract: The fast round robin circuit includes AND gates, OR gates, multiplexers and four D flip-flop gates configured to handle requests using linear propagation of a single grant token. In this manner the device avoids wasting clock cycles when some of the arbitrated entities do not have a pending request. The circuit has an R stage and an S stage. The R stage contains the request signal and an R memorization element to memorize the request. The S stage is the arbitration stage where the next active request is selected based on the position of the current request. The selection is then memorized in an S selection bit memorization element. There is one request signal and one pair of R and S Flip-Flops associated to every requesting entity. The selection circuit skips inactive requests to enable the next active request in a polling direction defined by the circuit.
