Abstract: A system for a trend-based guessing game includes an electronic communication and display device, configured with software to enable the electronic communication and display device to communicate with a cloud server that accesses a trend database to download a trend. The system also includes a pair of glasses configured to be worn by a user, the glasses including communication and display driver electronics and a glasses electronic display configured to display the downloaded trend on the glasses electronic display, the glasses electronic display configured such that the user cannot read the display when wearing the glasses.

Abstract: A system for preheating a catalytic converter includes a catalytic converter. The system also includes an inductive heating device coupled with the catalytic converter and configured to heat the catalytic converter with inductive heating. The system further includes a primary battery coupled to the inductive heating device and configured to selectively provide power to the inductive heating device. Further still, the system includes a secondary battery coupled to the inductive heating device and configured to selectively provide power to the inductive heating device. Yet further still, the system includes a microcontroller configured to provide signaling which causes switching of powering of the inductive heating device between the primary battery and the secondary battery.

Abstract: One embodiment of system that proactively protects computers from storm-related electrical damage. System includes chassis housing microchip and circuitry; software application installed on computer; and cloud-based server. Server scans online weather services for local weather alerts. When server sends alert to software application, based on computer location, application turns computer off and wirelessly instructs chassis to disconnect computer from power supply—before storm arrives. One embodiment uses a hub-and-spoke workflow that periodically scans once and routes alerts to users' software applications in affected locations only. Protection system scans every few minutes so even fast-moving storms are not missed, yet system neither overloads weather service servers nor incurs excessive usage fees. System also protects other appliances with wireless connectivity.

Abstract: The present invention consists of a container, made of fabric or wire-mesh netting, which attaches over a handgun's ejection port, and catches empty shell casings ejected when the weapon is fired. An opening at the bottom of the container, controlled by a drawstring and cord-lock, enables shells to be emptied without the need to detach the bag from the pistol's ejection port.

Abstract: A software application (FIG. 1) whose cloud component (FIG. 1.202) obtains bad-weather alerts (FIG. 2.200) from one or more online weather service (FIG. 3.400) and delivers them to the computer-based components of affected users. The computer-based program, wirelessly communicating (FIG. 9.900) with a hardware chassis component (FIG. 4.400), turns off the computer and then, using a relay switch (FIG. 11.300) in the chassis circuitry, virtually unplugs the machine. This offers proactive, remote protection to unattended, plugged-in computers, networks, tablets, smartphones and other devices against power surges and outages caused by bad weather. Good protection: a shut-down computer; best protection: an unplugged computer. The software is multi-platform, available for Windows and Mac computers, networks, laptops and tablets, as well as iPhones and smartphones.
