A head covering air filtering device containing a rigid component including a transparent face shield, a fabric component, wherein the rigid component and the fabric component combine to cover an entire head of a user and form a seal around the user's neck. The device further includes an intake filter to filter all intake air entering the device, an exhaust filter to filter all exhaust air exiting the device, and an air mover causing intake air to enter the device and exhaust air to exit the device.

Head covering device providing filtered intake and exhaust air

A personal air filtering device comprising a rigid component comprising a transparent face shield, a fabric component, wherein the face shield and fabric combine to cover an entire head of a user and form a seal around the user's neck, an intake port with an inlet filter, an exhaust port with an exhaust filter, an air mover causing filtered air to enter the intake port from outside the device and exhaust air to exit the exhaust port, and a controller configured to adjust the rate at which the air mover moves air.

Personal air filtering device with automatic control of air movement

A vehicle for delivering packages, comprising a tractor comprising a motor, a pair of front wheels, a rear wheel, and a rail between the pair of front wheels and the rear wheel, and a removable container comprising a space for storing packages where a bottom of the container is configured to fit over and mount to the rail.

Package delivery vehicle

A system for delivering packages from a warehouse to end destinations, the system comprising a fleet of self-propelled long-range transports and a fleet of containers, each configured to be loaded at the warehouse with packages destined for end destinations. Each long-range transport is configured to be loaded with at least four of the loaded containers and transport the at least four of the loaded containers from the warehouse to one or more intermediate destinations. Upon arrival of one of the loaded long-range transports at one of the one or more intermediate destinations, at least one of the loaded containers is separated from the loaded long-range transport, whereupon the separated container delivers packages to end destinations proximate to the one of the one or more intermediate destinations. After delivery of at least some of the packages loaded thereon at the warehouse, the container is once again loaded on the long-range transport and returned to the warehouse to be loaded with more packages.

Package delivery system

A personal air filtration system comprising a rigid component, a flexible component, wherein the rigid component and the flexible component combine to cover at least a user's mouth and nostrils and form a seal therearound, an intake port with an inlet filter, an exhaust port, an air mover causing filtered air to enter the intake port and exhaust air to exit the exhaust port, and an app running on a user's smart device, wherein a smart app is configured to control and monitor operation of the system.

Personal air filtration system with smart app

An apparatus including mechanisms for holding or guiding a fence post (or other type of post), in an essentially vertical orientation and in a relatively loose manner so that the apparatus can readily be removed part way through the post-driving activity and so that the downward driving force does not damage the apparatus. The apparatus is expandable from a compact transport configuration to a free-standing use configuration, and includes an assembly head having a connecting means for connecting a pair of pivotable 1st and 2nd support legs (each having a foot end and having an apex end pivotably connected to the assembly head and essentially opposing the apex end of the other support leg); a 3rd pivotable support leg having a 3rd foot end and a 3rd apex end pivotably connected to the assembly head (and enabling the apparatus to stand when all three support legs are pivoted outwardly); and a stabilizer support downstanding from the assembly head, and including a lower connection end. The apparatus also includes a stabilizer guide member having a middle portion pivotably connected to said lower connection end of said stabilizer support; a stabilizer end pivotably connected to said 3rd support leg; and an opposite guide end defining an aperture sized to accept insertion of the fence post in a manner positioning it essentially vertically for commencement of the user manually driving it into the ground but facilitating lifting of the apparatus off the partially driven post without altering the vertical positioning thereof.

Post driving guide

A fleet for delivering packages comprising a first number of containers, each container comprising at least one compartment for receiving packages at a main distribution center. The container comprises a first attachment member on an outer surface and a second attachment member on an outer surface. The fleet comprises a second number of long-range transports, each long-range transport is configured to carry multiple containers from the main distribution center to an intermediate distribution center, each long-range transport comprising multiple first attachment receivers, whereby the multiple containers are attached to the long-range transports during transport from the main distribution center to the intermediate distribution center. The fleet comprises a third number of short-range tractors, each short-range tractor is configured to carry at least one container from the intermediate distribution center to delivery destinations for the packages in the container, each tractor comprising at least one second attachment receiver, whereby the at least one container is attached to the short-range tractor during transport from the intermediate distribution center to the delivery destinations and back to the intermediate distribution center. The third number is at least twice as large as the second number and wherein the first number is at least twice as large as the third number.

Fleet for delivering packages

The invention is a mobile fueling system for vehicles that includes a fleet of mobile fuel stations, such as trucks. Each mobile fuel station has at least one fuel reservoir adapted for storing either liquid fuel, gaseous fuel and electric fuel. The system also includes a data processing hub and a network providing wireless data communication between vehicles, the fleet of mobile fuel stations, and the data processing hub. The data processing hub receives vehicle data from vehicles and fleet data from each mobile fuel station over the network. The vehicle data is transmitted from a customer's smart device running a customer app. The data processing hub is configured to dispatch via the network the mobile fuel stations in the fleet to vehicles in need of fuel based on at least three of the following factors: vehicle fuel level, a vehicle fuel request, vehicle location, a vehicle owner stored fueling location preference, a vehicle owner service request, reservoir fuel contents, reservoir fuel level and mobile fuel station location.

Mobile vehicle fueling system

A latching device with a blocking device that is capable of preventing unintentional opening of a door or a flap in the case of a crash. The blocking device includes a pyrotechnic gas generator. The pyrotechnic gas generator triggers in the case of a crash and moves a blocking element into a blocking position which prevents opening of the locking mechanism of the latching device.

Motor vehicle latching system with pyrotechnic blocking device

A control circuit for a fluid-filled heating pad is described. The control circuit is unique in that it includes a thermistor that is located in close proximity to the heating pad. The circuit is also unique in that it includes a single high-precision reference resistor to self-calibrate the control circuitry.
