An implantable infusion pump possesses operational functionality that is, at least in part, controlled by software operating in two processor ICs which are configured to perform some different and some duplicate functions. The pump exchanges messages with an external device via telemetry. Each processor controls a different part of the drug infusion mechanism such that both processors must agree on the appropriateness of drug delivery for infusion to occur. Delivery accumulators are incremented and decremented with delivery requests and with deliveries made. When accumulated amounts reach or exceed, quantized deliverable amounts, infusion is made to occur. The accumulators are capable of being incremented by two or more independent types of delivery requests. Operational modes of the infusion device are changed automatically in view of various system errors that are trapped, various system alarm conditions that are detected, and when excess periods of time lapse between pump and external device interactions.

A device with mass storage capability that uses a readily available non secure memory for the mass storage but has firmware (and hardware) that provides security against unauthorized copying of data. This is true even though the firmware itself is stored in the non secure mass storage memory, and therefore potentially vulnerable to hacking. An indication of the authenticity of the firmware must be present before it will be executed by the device. This protects the device contents from unauthorized duplication or tampering. Additional functionality can be added to the device with additional firmware applications, and the authenticity of those additional applications will also be verified before they will be executed. This further prevents unauthorized copying or tampering of secure content through any mechanisms that may be unscrupulously introduced. Any data within the mass storage memory may also be encrypted.

A Drill-To-The-Limit (DTTL) drilling method variant to Managed Pressure Drilling (MPD) applies constant surface backpressure, whether the mud is circulating (choke valve open) or not (choke valve closed). Because of the constant application of surface backpressure, the DTTL method can use lighter mud weight that still has the cutting carrying ability to keep the borehole clean. The DTTL method identifies the weakest component of the pressure containment system, such as the fracture pressure of the formation or the casing shoe leak off test (LOT). With a higher pressure rated RCD, such as 5,000 psi (34,474 kPa) dynamic or working pressure and 10,000 psi (68,948 kPa) static pressure, the limitation will generally be the fracture pressure of the formation or the LOT. In the DTTL method, since surface backpressure is constantly applied, the pore pressure limitation of the conventional drilling window can be disregarded in developing the fluid and drilling programs. Using the DTTL method a deeper wellbore can be drilled with larger resulting end tubulars, such as casings and production liners, than had been capable with conventional MPD applications.

Systems and methods for interruptible autonomous control of a vehicle. Autonomous control is achieved by using actuators that interact with input devices in the vehicle. The actuators (e.g., linkages) manipulate the input devices (e.g., articulation controls and drive controls, such as a throttle, brake, tie rods, steering gear, throttle lever, or accelerator) to direct the operation of the vehicle. Although operating autonomously, manual operation of the vehicle is possible following the detection of events that suggest manual control is desired. Subsequent autonomous control may be permitted, permitted after a prescribed delay, or prevented.

A fixed-wing VTOL aircraft features an array of electric lift fans distributed over the surface of the aircraft. A generator is (selectively) coupled to the gas turbine engine of the aircraft. During VTOL operation of the aircraft, the engine drives the generator to generate electricity to power the lifting fans. Power to the lifting fans is reduced as the aircraft gains forward speed and is increasingly supported by the wings.

A high-pressure wear resistant cylinder that utilizes a high-pressure field for strength is an economical method of, or device for, handling very high pressures and the pumping of abrasive and corrosive fluids. The economic considerations are so favorable, that the invention may be considered a replacement part. The invention is suitable for a variety of applications, particularly a reciprocating flow work exchanger in the well stimulation or hydraulic fracturing industry. Using a high pressure field to strengthen the external surface (outside) of a pipe that is precision honed and plated or sleeved internally (inside), it is now possible to construct various high pressure machines in a relatively inexpensive manner. This invention makes it possible to use pipe with internal operating pressures greater than their nominal operating pressure ratings permit. This invention will be used in various high pressure piping and machinery applications.

A system and method of controlling quadrotor air vehicles (QRAV) that may include an additional two degrees of freedom for each of the four propellers of the QRAV. Each of the four rotors may be allowed to rotate (tilt) around two local axes selected from the x-axis (roll), y-axis (pitch), and z-axis (yaw). Control of the quadrotor including the additional two degrees of freedom allows thrust of each rotor to be direct in any direction of a semi-sphere. As a result, total control inputs of the QRAV may be increased to twelve, enabling smooth control to achieve superior and precise maneuverability. Additionally, the system and method is fault tolerant and capable of handling failures of any of the rotors. Commands to the propellers may be fully decoupled and achieved independently thereby giving pilots better control to execute difficult maneuvers.

A Wireless LAN Context Control Protocol (WLCCP) is used to establish and manage a wireless network topology and securely manages the “operational context” for mobile stations in a campus network. The WLCCP registration protocol can automatically create and delete links in the network, securely distribute operational context, and reliably establish Layer 2 forwarding paths on wireless links. A single infrastructure node is established as the central control point for each subnet, and enables APs and MNs to select the parent node that provides the “least-cost path” to a backbone LAN. Context messages provide a general-purpose transport for context and management information. WLCCP “Trace” messages facilitate network diagnostic tools. Ethernet or UDP / IP encapsulation can be used for WLCCP messages. Ethernet encapsulation is employed for intra-subnet (e.g. AP-to-AP or AP-to-SCM) WLCCP messages. IP encapsulation is used for inter-subnet WLCCP messages and may also be used for intra-subnet WLCCP messages.

In a further embodiment, the system can be coupled to various elements of the motive system to create an auto-starting car.
