Filed:

Jan 14, 2004

Appl. No.:

10/757582

Inventors:

Joseph Lai - San Pedro CA, US

International Classification:

G08B 1/00

US Classification:

3403097, 3403841, 368109, 368110

Abstract:

This present invention is for new user-friendly electronic pill reminder devices that convert regular conventional pill bottles to automatic reminder pill bottles. The reminder device is compatible and can be retrofitted inside a regular conventional pill bottle cap. This reminder device is installed inside the conventional pill bottle between the bottle cap and the bottle container. When the user closes the pill bottle cap on the bottle container, the electronic timer, with factory predetermined time interval, is automatically activated. That activated timer will generate alert signals not only remind user last pill has taken but also to remind the user to take his/hers next dose at time-out. The reminder device and alert signals are automatically deactivated and reset when the user opens the pill bottle cap (to take contents from the bottle container). This present reminder device works with both conventional safety (child-resistant) and non-safety pill bottle caps.

Inventors:

Joseph Lai - San Pedro CA, US

International Classification:

H01R 12/00

US Classification:

439 66

Abstract:

A new user-friendly USB (Universal Serial Bus) male connector is physically and functionally compatible to the existing and future USB female connectors. Unlike the conventional keyed, polarized and position dependent USB male connector. The new user-friendly USB male connector provides spare connections, eliminates potential connector damage and allows normal and opposite insertions to the USB female connectors.

International Classification:

H04N 7/173

US Classification:

725127, 725126, 725149, 348558, 348465, 348467, 375316, 375346

Abstract:

A downstream bandwidth output level and/or output level tilt compensation device that can be inserted into a signal transmission line of a CATV system on a premise of a user. The device includes a tuner that identifies low and high band signal channels, and a channel analyzer that determines a format of each of those channels. A signal measurement measures low and high band signal strengths. An offset circuit adds or subtracts an offset value to the low and/or high band channel signal strengths depending on whether the respective channel is analog or digital. A microprocessor compares the low and high band signal strengths, including any offset values, to a predetermined signal strength loss curve. A variable output level compensation device and a variable slope adjusting circuit are provided to amplify and adjust the gain slope of the downstream bandwidth.

Abstract:

An upstream bandwidth conditioning premise device for use as part of a CATV system and for placement on or near a user's premise to reduce noise created on the user's premise that would otherwise be injected into upstream transmission channels and passed into an RF main signal distribution system of the CATV system. The device includes a variable attenuation device, a signal measurement circuit, a memory circuit and an electronic circuit, which is configured to iteratively determine (i) whether an incremental amount of additional attenuation is to be applied and (ii) whether at least a portion of a previously applied incremental amount of attenuation is to be removed. The electronic circuit includes a counting circuit, a threshold comparison circuit configured to compare a peak signal strength to a predetermined threshold, and a peak comparison circuit configured to compare a contemporary peak signal strength to a previous peak signal strength.

Inventors:

Joseph Lai - San Pedro CA, US

International Classification:

G08B001/08

US Classification:

340539150, 340573100

Abstract:

A disguised Emergency Locator Transmitter (ELT) device for kids, works as LoJack™ for cars, is installed inside kids' belongings, such as clothes, small toys, dolls, and handheld electronic LCD video games (or as LCD video game cartridges) with built-in GPS receiver and cellular phone for locating kids in case of emergency. Preprogrammed phone numbers such as 911 or parents' phone numbers are dialed with location information when the ELT is powered and activated by recognizing the keystrokes, voice commands or remotely via the cellular phone or paging networks. The kid and the ELT devices will be located by GPS and/or triangulation of the cellular phone or paging base-station towers.

International Classification:

H04N 7/00

US Classification:

725118

Abstract:

A frequency band selection device that can be inserted into a signal transmission line of a CATV system on the premise of a user includes at least two signal path sets between a tap side and a premise side. Each signal path set includes two discrete signal paths, a high frequency signal path for a downstream bandwidth and a low frequency signal path for an upstream bandwidth. The high frequency signal path and the low frequency signal path are separated by a cut-off transition frequency that is different for each signal path set. The device further includes a switch controller having at least two discrete switch positions. The switch controller chooses one of the switch positions as a result of an information signal. Each of the switch positions corresponds to a respective one of the signal path sets.
