ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to portable power supply systems and, more specifically, to a portable, self-contained solar powered CD player and electrical generator and that utilizes a top-mounted solar panel to collect solar energy and then converts that solar energy into electrical energy to be stored in a rechargeable battery or used to power accessory components that are integrated into the unit such as an AM/FM radio, lantern, CD player, etc. A DC to AC inverter and an AC outlet are included to allow for operation of an AC powered device that is plugged into the unit.

A vest garment to be worn by persons working out of doors and which has an array of photovoltaic cells mounted on the back panel thereof. The individual cells are connected in series relationship with one another across a pair of output terminals which are brought out through a belt attached along the waistband of the vest to an output jack. The voltage developed across the photocell array may then be used to charge rechargeable batteries suspended from the belt or, alternatively, they be coupled to an input jack of a power tool having a self-contained rechargeable battery whereby charging current is generated when the vest is being worn out of doors.

A portable high pressure sodium lamp lighting system is mounted on a mobile cart, the cart carrying a mobile power supply in the form of an automotive type battery. The portable lighting system employs a standard high pressure sodium luminaire designed to be driven by 115 volt 60 cycle utility generated power. A DC to AC converter is employed which converts the DC battery supply to a 115 volt simulated 60 cycle supply. The AC characteristic is simulated by generating a quasi-square wave form which approximates a 60 cycle characteristic when driving the luminaire.

A portable power supply having a rechargeable battery in a housing mounted on a portable frame. An inverter/converter unit, attached to the frame, is hardwired to the battery for conversion of DC power to AC power and for recharging the battery from an external AC source. Power distribution means are provided for distributing DC and AC Power. Photovoltaic panels are mounted to the frame for recharging the battery.

A portable radio telephone handset includes the capability of operating as a data transfer terminal as well as an analog cellular telephone subscriber station. Two modes of operation are available in the handset, and a analog cellular communication mode and a Cellular Digital Packet Data (CDPD) mode. A controlled processor in the handset is used to program the power supply to follow a prioritized, high efficiency operating cycle, preferably tracking CDPD active/sleep mode duty cycle. The power supply has the capability of providing 120 volts AC output for other communication systems. The availability of 120 volts output is programmed to track the functions of the CDPD operation and Advanced Mobile Phone Service (AMPS) operation.

A power supply device and system for providing power to a portable electronic device. A detachable device includes a rechargeable DC power source, a DC-to-AC inverter, and a primary transformer winding around a first core element. The portable electronic device includes multiple secondary transformer windings around a second core element. The detachable device cooperates with the portable electronic device so as to form a complete power supply circuit for providing AC and/or DC operating voltages to the portable electronic device.

A Portable Power System configured to supply an appropriate voltage to an electrical device. The system includes a battery pack having at least one cell supplying a first direct current voltage, and an adapter. The adapter, which is electrically connected to the battery pack by an electrical cord, is configured to be mechanically connected to the device. The adapter also includes a DC to DC voltage converter supplying a second direct current voltage to the device, the second voltage being smaller than the first voltage but sufficient to permit the intended operation of the device.
While these portable power supply systems may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.
SUMMARY OF THE PRESENT INVENTION
The present invention discloses a portable, self-contained CD player and radio having a solar energy collection, conversion and storage system as a primary power source with a DC to AC inverter that provides the present invention with the capability of powering AC dependent devices. The solar energy is collected by a solar panel that is pivotably attached to the topside of the device and can be adjusted to an angle sufficient to maximize the suns rays. To further increase the potential power output of the present invention remote solar panel arrays having a telescoping adjustable tripod can also be connected to the device. The solar panels are pivotably and rotatably affixed to the tripod to allow precise adjustment for effective solar energy collection. The solar panel array and tripod can be broken down for transport and storage as a single unit and the solar panels are sequentially offset from the tripod to permit the panels to swing face-to-face into an evenly stacked position to maintain the portability of the present invention.
A primary object of the present invention is to provide a self-contained, portable AM/FM radio and CD player having a solar energy collection and conversion system as the primary power source.
Another object of the present invention is to provide a portable, solar-powered CD player having a rechargeable battery that can store energy cultivated from the solar panel or energy obtained from an external source such as a 110 VAC outlet or a 9 VDC automobile lighter.
Yet another object of the present invention is to provide a portable, solar-powered CD player having a DC to AC inverter and an AC outlet to allow a user to operate an AC dependent device such as a television or a power tool.
Still yet another object of the present invention is to provide a portable, solar-po
