  • Patent number: 11162715
    Abstract: Standalone and self-contained cooling systems using compressed liquid and/or gas CO2 containers positioned in an insulated or non-insulated vessel encompassing a container which is either vertically positioned in an upright or an upside-down position. The liquid and/or gas CO2 coolant is then released into a capillary system or flow metering system to allow the CO2 to enter a second body to where the CO2 coolant properties may be leveraged. The second body includes, by way of example, a plate, a cushion, a spot treatment pad for a person's muscle, or a cooler. The temperature is controlled by a metering CO2 releasing system encompassing an electronic control device which sends alerts when pre-defined thresholds are exceeded. The invention's metering CO2 releasing system may be triggered by an electronic or a thermostatic valve or may be triggered manually or by an electronic solenoid.

  • Patent number: 10345015
    Abstract: Standalone and self-contained cooling systems using compressed liquid and/or gas CO2 containers positioned in an insulated or non-insulated vessel and consisting of a specially designed unit where the containers are vertically positioned in an upright or upside-down position. The liquid and/or gas CO2 coolant is then released into capillary tube(s) embedded into a heat transfer plate or heat exchanger thus leveraging the CO2 coolant properties. The temperature is controlled by a metering CO2 releasing system encompassing an electronic control device which can be operated remotely and/or via a touch screen and which sends alerts when pre-defined thresholds are exceeded. The invention's metering CO2 releasing system may be triggered by an electronic or a thermostatic valve or may be triggered manually or by an electronic solenoid. The invention's cooling system also encompasses check valves, which avoid liquid and/or gas CO2 from escaping when removing or replacing CO2 containers individually.

  • Patent number: 9349287
    Abstract: An embedded Tire Pressure Monitoring sensor is incorporated into vehicular wheels and a secured central server is used to track the unique identification code of each sensor. The TPMS is installed by the vehicular manufacturer in accordance with the federally mandated TREAD Act of 2000. When a vehicle enters the radius of a first encrypted TPM sensor detection transceiver, its TPM sensor identification codes are recorded and time-stamped via an encrypted TPM sensor detection transceiver. If the vehicle enters the area of a second encrypted TPM sensor detection transceiver, the sensor codes will be recorded and time-stamped a second time, encrypted and sent to the secured central server. Using the two encrypted, time-stamped signals, the secured central server calculates traffic flow data.

  • Publication number: 20160005311
    Abstract: An encrypted traffic signal device controller (TSDC) and an Electronic Variable Message Sign (EVMS) at intersection roadways and related traffic intersections where the invention system is installed at traffic light intersections which will be triggered at the red light sequence where vehicles/pedestrian/cyclists are stopped. After the traffic light turns red, the time delay of the red light will trigger an audio and visual public announcement which will be of assistance to the driver and enable the driver to pay attention to the announcement without being concerned about diverting the driver's attention from driving the vehicle since the vehicle is stopped at a red light and the driver can devote his attention to reading the information provided.
